Multiplication does not take precedence over division

Addition does not take precedence over subtraction

i wast meaning it took precedent i was just saying it as an order you can do it in... if you know PEMDAS you know what it means

and 2 is not the correct answer... you have to expand the equation out first

ok seriously people look at the equation attached, that is the SAME THING...

post-47883-0-23861600-1303932695.png

now what do you multiple bu there? the 2 or 48/2? take a guess 48/2 is a single entity, you have to multiply the result of it by the next part..... how hard is this to understand?

I'm starting to think I need to add something this simple question onto interview tests sheesh....... weed out a lot of people fast by the looks of it

If you got as far as Elementary school or didn't take Pre-Algebra until the 10th grade then yes 48 ? 2(9+2) does indeed equal to 2. With Basic math, the order would be going to the right to left. thus 48/24=2

If you understand Mathematics beyond Algebra, then 48 ? 2(9+3) is 288

What you need to do is first Parenthesis 48/2*(9+3) = 48/2*12 ok now we solve it going LEFT TO RIGHT 48/2=24*12=288

48/2=24x12=288 :shiftyninja:

you're hired, you at least understand order of operation and LTR

Easy.

Highlight the text, right-click, select Search Google for '48?2(9+3)'

HAHAHAHA, good call. The first hit on Google is that this question is used to troll forums because there are two possible answers, and it's funny to see people argue about it.

Nice job OP! LOLOLOLOL

Makes you wonder when people start arguing about the very basic order of operations. I would much rather see a discussion and arguments on tupper's self-referential formula. :whistle:

ROFL after looking at the google search, I found this yahoo answers

Distributive property of multiplication. Early Algebra.

The distributive property of multiplication CLEARLY states that the 2(9+3) is an entire term and CANNOT be broken up. 2(9+3) follows the distributive property which can be rewritten as (2*9+2*3). Let me repeat the 2 outside of the parenthesis follows the distributive property of multiplication and must be factored and simplified before performing any other operations on it.

So this can be rewritten as:

48 / (2*9 + 2*3)

Which leaves us with

48 / 24 = 2

Answer = 2.

Lastly for those using Google or any other online calculator. These do not understand many theorems or properties so you must explicitly explain what you mean. There is a difference between 48 / 2 *(9+3) and 48 / 2(9+3). The first notation reads 48 / 2 * 1(9+3) while the second reads 48 / (2*9+2*3). Be very careful with your signs.

Nobody argue about order of operations here. People argue if 2(9+3) should be considered as juxtaposition or a normal multiplication.

do we need to teach people order of operators again?

Parenthesis first

Exponents second

Multiplication third

Division fourth

Addition fifth

Subtraction sixth

48?2(9+3) turns into (48 / 2) * (9 + 3) which means do it in this order

(48 / 2) = 24

(9 + 3) = 12

24 * 12 = 288

you have to remember to "segment" operations off so when you do that it turns into this

( (48 / 2 ) ( 9 + 3) )

then

( ( 48 / 2) * ( 9 + 3 ))

then

( (24) * (12))

That's slightly incorrect. Multiplication and division carry the same weight, as do addition and subtraction. For example, 3 * 3 / 2 would be interpreted as (3 * 3) / 2, not 3 * (3 / 2), even though the result is the same. The order of operations is solved left to right for these operators.

Also, the equation does NOT become "(48 / 2) * (9 + 3)" .. the 9 + 3 is in brackets so that part is solved first.

The equation is solved like this:

(9 + 3) = 12

48 / 2 = 24

24 * (12) = 288

In school we were taught "BODMAS" (Brackets Order Division Multiplication Addition Subtraction) .. the fact that we were taught DIVISION MULTIPLICATION rather than MULTIPLICATION DIVISION like you further re-enforces the point that division and multiplication carry the same weight.

Also, if juxtaposition held any weight like many people in this thread say it does then I'm pretty sure it would be taught in school. Even though it's basic maths taught in school, doesn't mean they're going to teach us wrong information!

These idiots are tying to say that 48/2*(9+3) is not the same as 48/2(9+3) LOL.

THIS IS THE CORRECT WAY ------->. NOT <----------.

For 2(9+3) to be interpreted as (2*9+2*3) it would need to be enclosed in brackets. You solve what is in brackets first, then you solve exponents, then multiplication/division, then addition/subtraction, in a left to right order.

In other words the way the equation is written, you would not interpret 2(9+3) BEFORE you interpreted 48/2, because it is further along in the equation than 48/2. You interpret (9+3) first, by itself. If the equation was 48/(2(9+3)) then the answer would be 2. But there are no brackets enclosing the 2(9+3), so the answer is 288.

Easy peasy.

The answer is how you display the equation.

48

-- (9+3) = 288

2

48

--------- = 2

2(9+3)

I believe the second way is the proper way.

The hitler parody posted in this thread says it all: "Where in the bodmas rule does it say that multiplication by juxtaposition takes precedence over other multiplication and division?" ANSWER: it does not.

;)

Correct answer

No it is not

48?2(9+3)

means

48 divided by 2 times the answer of 9+3 - this is standard math procedure, there is no misinterpretation of this this is the way that all math flows.

now if the question were phrased like this

48?2

(9+3)

then the answer would be 2, but it wasn't phrased like that so the answer is 244

2(9+3) means to multiply 2 times the number that 9+3 equals or to multiply 9 two times and multiply 3 two times and add those two numbers together. but if you have an equasion followed by the parenthesis, it is always the result of the equasion multiplied by the answer within the parenthesis. There is no division, it is always multiplied unless it is over another with the example I gave or with a /. This is the way it exists with all math problems, if you think otherwise you need to go back to high school algebra possibly even 6th grade math.

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.

Since when does multiplication by juxtaposition get solved before other multiplication and division?

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

Since when does multiplication by juxtaposition get solved before other multiplication and division?

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

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

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

    • 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.
