the answer is 2 my noob friends :) 48/2(9+3) 9+3=12 its not done yet, 12 inside parenthesis is multiplying by 2. you have to keep simplyfing until its done. 12*2 =24 48/24 = 2. even with the distribution... 2*9 + 2*3 2 is part of it and must be dealt with first and simplified - 18 + 6 = 24. 48/24 = 2. You people getting 288 or whatever are wrong.

So do you trust a calculator more than a human?

How bout multiple calculators? in the second image I didn't add the * between the 48/2 and the (, it did that automagically. So every calculator is wrong in the world and a few people that really don't understand the order of operations is right?

The Distributive Property in ALgebra:

The Distributive Property is handy to help you get rid of parentheses.

a(b + c) = ab + ac

To multiply in algebra, you'll use the distributive law:

3x(x+4)

= 3x(x) + 3x(4)

=3x2+12x

i know the order, and so do you. You just arent finishing the operation. which is why u keep coming up with the wrong answer

you have to get rid of the parenthesis... just saying 9+3=12 doesnt get rid of the parenthesis. continuing to simplify gets rid of the parenthesis. hence you have to multiply 12*2

It seems to me like two laws are competing against each other, because according to the order of operations (9+3) should be solved first, NOT 2(9+3), yet according to the distributive property, 2(9+3) should be solved as one symbol, but this goes against the order of operations.

Clearly the distributive property needs to be incorporated into BODMAS/PEMDAS/whatever.

But as it stands.. I stick with 288!

With order of operations multiplication and division are the same then you go from right to left. Thats how you get 288

48/2(12) goes to 24 x 12 = 288

Look up the order of operations OR type this into a calculator and you will get 288

LOL calculators don't really do algebra problems really well.... or all of you would have gotten an a in algebra ;) once you use the distributive property and simplify it.. then u can type it in the calculator for an answer of 2

You can go left to right provided you understand what is happening.

left to right

48/2 = 24 (are you following me so far?)

stop we have parenthesis so we know from standard math procedure we must do that next

9+3 = 12 (are you still following me? we are still doing this left to right nothing really has changed)

so in reality, it is 24(12). What does this mean?

It means we take 24 and multiply it by 12 (not divide), which brings the answer to 288. All this by working left to right and understanding what the parenthesis are.

I did, got honers actually....scientific calculators do algebra quite well actually (but they don't tell you that in algebra) and at the time I took algebra the cheapest scientific calculator was over $100.

48/2 is NOT solved before the brackets.

the brackets do not disappear, it doesn't matter if you do the first portion first or second, the brackets do not disappear.

you do left to right unless otherwise instructed. the brackets do not go away.

This is how I read this, and most people in the world do (even the calculators disagree with you that are designed to specifically work with these types of problems).

48?2(9+3)=

48 ? 2 x (9 + 3)=

(48 ? 2) x (9 + 3)=

You solve left to right, with any math problem. the parenthesis do not go away with the 9+3 that is a whole answer. the 48/2 is a whole answer. once you solve the first part 48/2 you can continue on to mulitply it by the 9+3 answer.

You can go left to right provided you understand what is happening.

yes im following you. but you can do 48/anything until u get rid of the parethesis using the distributive property

But as it stands.. I stick with 288!

they are not competing with each other. if u solve 9+3 = 12. you still did not get rid of the parenthesis. you have (12) in order to get rid of the parenthesis you have to multiply that 12 by 2. hence the distribution property. 2(9+3) 2*9+2*3

So do you trust a calculator more than a human?

How bout multiple calculators? in the second image I didn't add the * between the 48/2 and the (, it did that automagically. So every calculator is wrong in the world and a few people that really don't understand the order of operations is right?

I trust calculators. you are just doing it wrong. you have to get rid of the parenthesis first. type this into your calculator 2(9+3) get your answer. then do it from left to right

2(9+3) isn't the whole question. You are doing it wrong if you think it is.

The question eventually becomes

24(12)

Type that into your calc. The 2 isn't in brackets encompassing the (9+3) so 2(9+3) is not correct.

It isn't 48/[2(9+3)] then your answer would be correct.

I trust calculators. you are just doing it wrong. you have to get rid of the parenthesis first. type this into your calculator 2(9+3) get your answer. then do it from left to right

There's no argument that 2(9+3) on its' own = 24. The argument is whether the equation should be interpreted as 48/2*(9+3) or 48/(2(9+3))

hehe, its all good. i know im right. their is no need to get personal or anything. i am using order of operations. parenthesis is the first thing u take care of, and they do dissapear. If you dont believe me... thats fine. Do the research.. take it to your math teacher - its all good. but the distributive property is how you multiply in algebra. the distributive property gets rid of the parenthesis, which is the first operation. otherwise, its all good. i enjoyed this topic ;) Have a good night my computer friends... and remember.. its almost time for ubuntu 11.04!!

The brackets do disappear and the equation is still simplified, but not in the order that you suggest.

(9+3) = (12)

48 / 2 = 24

24(12) = 24*12 = 288

yea thats wrong. (9+3) = (12) the brackets are still there. they have to be gone before u continue. 12 inside the bracets means it is multiplying by something(keep simplyfing) . I know what you are saying, you are just wrong. you are just making up your own rules. I dont think you ever even took algebra before ;) the order i suggest is p first... you know, pemdas

in your way... you never take care of the parentheses. you do it last? how is that right? what order of ops are you using? and yes u have to get rid of the parenthesis, thats what the whole distributive property is all about

ok you guys are right. the distributive property is wrong. when u finally take algebra for the first time... just type all the problems as u see them right into the calculator before putting the equation into correct form.... and watch yourself get an f

Okay you're right, the order of operations is wrong.. when you finally take basic maths for the first time.. watch yourself get an f.

You see? There are arguments for both sides. The more I think about it the more I think that it's an incorrectly written equation. The distributive property means you need to simplify 2(9+3), BUT, that goes against the order of operations because you are solving a multiplication on the right before you solve a division on the left.

I think it NEEDS to be written as either 48/(2(9+3)) OR 48/2*(9+3), both of which can be solved without ambiguity.

It seems like a contradictory equation.

Interpreting it as 48/2*(9+3) ignores the distributive property.

Interpreting it as 48/(2(9+3)) ignores the order of operations.

their is no argument for the other side. the other side is wrong, and the eqation is fine. if the other side was right... the equation would look like this 48/2*12. but its not. its an algebra problem because of the parenthesis which means you use the distributive property. a(b+c) = a*b+a*c. You guys will understand this when you finally take algebra for the first time ;)

The order of ops exists in algebra too, you don't just forget about it.

The majority of the people here are right and the calcs agree with them. Calcs are based on programming done by people much smarter than all of us. Either the mathematicians that were involved in programming every scientific calculator are wrong or the few that are saying 2 are wrong. My money is on the calcs and my teachings which agree with the calcs as well as the all knowing google.

    • Lexar PLAY X 1TB 2230 review: blazing fast PCIe Gen4x4 gaming SSD for PC and consoles by Steven Parker Lexar reached out to us asking if we were interested in taking a look at the Lexar PLAY X SSD. This drive is mostly (but not strictly) intended for handhelds and consoles as a means to expand storage for gaming, but you can use it however you like. In our case we were sent the 2230 1TB variant, so we plopped it into the bracket that's included in the box and installed it in our test PC. Before we get underway, Lexar provided a free sample without any editorial input or review pre-approval. Below are its specifications: Lexar PLAY X Interface PCIe Gen4x4 with NVMe Form Factor M.2 2030, M.2 2230, M.2 2280 Capacity 512GB, 1TB, 2TB Speed 512GB: Sequential read speed up to 7200MB/s, sequential write speed up to 4500MB/s, random read up to 900K IOPs, random write up to 900K IOPs 1TB: Sequential read speed up to 7400MB/s, sequential write speed up to 6400MB/s, random read up to 1000K IOPs, random write up to 1000K IOPs 2TB: Sequential read speed up to 7400MB/s, sequential write speed up to 6500MB/s, random read up to 1000K IOPs, random write up to 1000K IOPs DRAM Cache No TB written 512GB: 300TBW, 1TB: 600TBW, 2TB: 1200TBW Operation temp 0° to 70°C (32°F to 158°F) Storage temp - 40° to 85°C (- 40°F to 185°F) Durability Shock Resistance: 1500G, duration 0.5ms, Half Sine Wave Vibration resistenence: 10~2000Hz, 1.5mm, 20G, 1Oct/min, 30min/axis (X, Y, Z) MTBF 1,500,000 Hours Dimensions 80 x 22 x 2.45 mm / 3.15”x0.87”x0.10” Weight 9.5g / 0.02lbs Part nr LNMPLYX001T-RNNNG Warranty 5 years Price £119.99, €119.99, / £218.99, €249.99 First a few notes about the specs. The Lexar PLAY X SSD does not come with a (graphene) heatsink so you will have to ensure you have a thermal pad or something that can be used with this drive, and secondly it says in the specs that it does not have a DRAM Cache, as it makes use of: Basically what this means is that HMB handles finding files, while the Dynamic pseudo-SLC cache handles writing them. The Lexar PLAY X uses TLC NAND flash memory, which stores three bits of data per cell. Writing three bits requires checking multiple voltage levels, which takes time. It's a trade off for the drive size too, as it would be difficult to place DRAM cache onto the 2230 format. What's in the box Lexar PLAY X (1TB) 2280 Bracket 2230 and 2280 Sticker Quick Installation Guide Our test system consists of the following: Lian Li O11 Dynamic Mini V2 Flow (Amazon|Newegg) ASUS ProArt Z890-CREATOR WiFi (Amazon|Newegg) Intel Core Ultra 7 270K Plus (Amazon|Newegg) Thermal Grizzly KryoSheet - 44x37 (Amazon|Newegg) 2x 16GB G.Skill Trident Z5 RGB (7200 MT/s in XMP) (Amazon|Newegg) Sabrent Rocket4 Plus 2TB SSD (Amazon) Windows 11 Pro 25H2 (Build 26100.8655) Benchmarks With that out of the way, we ran some benchmarks comparing (historic) data with a couple of other drives on a system that is up to date with the latest June Patch Tuesday updates. Aside from the clear difference between the PCIe 4x4 and PCIe 5x4 results, it is also clear that applying correct thermal conditions, in this case the DARK AirFlow I, makes a difference with the outcome of the score as can be seen on the TeamGroup Z540. (hsf = heatsink & fan, hs = heatsink) WD SN850X Lexar PLAY X Z540 with DARK AirFlow I In our 3DMark Storage benchmark test (images above), which measures access times and bandwidth for gaming scenarios, the Lexar PLAY X was the fastest. Even compared to the actively cooled TeamGroup Z540, this one was 23% faster, despite being on PCIe Gen4; and it was doing so while running cool too, as you will see later in our temperature stress test. The Lexar PLAY X supports DirectStorage like other NVMe drives, and here, the SSD was a lot better with DirectStorage enabled on our 3DMark DirectStorage feature test. With GDeflate especially, the improvement is tremendous. Overall, the test result says that the Lexar PLAY X was nearly three times faster while running with DirectStorage. (hsf = heatsink & fan, hs = heatsink) Z540 with DARK AirFlow I Lexar PLAY X WD SN850X Next we ran the default CrystalDiskMark test (images above) and measured the disk temperature. Even with the motherboard M.2 heatsink applied to the top of it, the drive managed to reach a peak of 70C, which is well within specification. Also, another positive is that it exceeded its advertised sequential write speed of 6,400 MB/s in our testing, which is rare and deserves praise. Z540 with DARK AirFlow I Lexar PLAY X WD SN850X The second test is of six passes at 16GB (images above), meant to stimulate a heavier, longer transfer session, and it reached the same max temp of 70~71C. This indicates that the PLAY X is performing exceptionally well even under heavy loads. It is not as chill as the WD_BLACK SN850X, but 70-71 C is completely safe. Usage Although Lexar generally markets anything stamped with "Play" for handhelds and consoles, on the official product page and Amazon listing, the PLAY X is definitely marketed as an all-rounder with the company claiming that it is: This is exactly what we did, as our sample was placed into the 2280 bracket and installed in the M.2_1 slot on our ASUS ProArt Z890-CREATOR WiFi. CrystalDiskInfo Idle temp as shown above is also pretty decent at 28C. Lexar DiskMaster Lexar also provides a disk utility that can read the disk information and benchmark it. S.M.A.R.T info can be viewed above and it loads automatically in the program, I also ran the "Performance testing" which gave a better result than we saw in CrystalDiskMark v9.0.2. Conclusion I have to say I came out very impressed with the PLAY X, especially seeing how well it did in the 3DMark gaming test. That was surprising for sure, in a good way of course. Hence, as the name suggests, the PLAY X can be a great drive for gaming rigs. The drive ran fairly cool as well, although you will want to make sure it's properly cooled, seeing how it was reaching its maximum recommended operating temperature; but there was no noticeable throttling. The 600 TBW rating of the 1TB variant seems pretty good as well for this gaming-orientated storage where writes will be happening more frequently for game saves and what-not, but even so, you should see years of use without any problems and even if you do run into problems, the five year warranty should have you covered. A bit of a downer for our U.S. readers though, Lexar told me that the PLAY X is not yet available to purchase in the United States, but it can be ordered if you're in the UK. I asked when they plan to release it there and was told: In addition, although the initial review documentation and official website suggests there is also a 2 TB variant, Lexar have stated that "The 2TB version has not been launched yet." As you can see from the links below, the 1 TB variant is also selling a bit above the RRP in the UK, and the 512 GB version aligns with Lexar's RRP. Lexar PLAY X 1 TB for £241.99 on Amazon UK Lexar PLAY X 512 GB for £119.99 on Amazon UK We hope the 2TB variant becomes available soon, considering how well the drive did in our game data tests. We feel the higher capacity will be popular for sure, though at this time, the lack of it is not hard to understand why, given the shortage and the shift in focus for a lot of companies.
