neufuse Veteran Posted April 27, 2011 Veteran Share Posted April 27, 2011 except as multiple people have pointed out through this thread, and any search will show you, that is incorrect PEDMAS Parenthsis Exponents Multiplication AND Division Addition AND Subtraction similarly BODMAS Brackets Orders Multiplication AND Division Addition AND Subtraction 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... 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 Link to comment Share on other sites More sharing options...
Lezard Posted April 27, 2011 Share Posted April 27, 2011 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: /Thread Link to comment Share on other sites More sharing options...

Peter Griffin Posted April 27, 2011 Share Posted April 27, 2011 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!

Lezard Posted April 27, 2011 Share Posted April 27, 2011 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 Best Answer - Chosen by Asker 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. Edited 3 weeks ago Link to comment Share on other sites More sharing options...

Hardcore Til I Die Posted April 27, 2011 Share Posted April 27, 2011 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! Link to comment Share on other sites More sharing options...
LaP Posted April 27, 2011 Share Posted April 27, 2011 you read an equation left to right in addition to order of operation, there is not "juxtaposition" in this Yet again many engineering books will consider 2() something as juxtaposition and to get the right answer you'll need to do it first.

Hardcore Til I Die Posted April 27, 2011 Share Posted April 27, 2011 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.

ruhgster Posted April 27, 2011 Share Posted April 27, 2011 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. Link to comment Share on other sites More sharing options...

sc302 Veteran Posted April 27, 2011 Veteran Share Posted April 27, 2011 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.

joint Posted April 27, 2011 Share Posted April 27, 2011 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. 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 Link to comment Share on other sites More sharing options...
joint Posted April 27, 2011 Share Posted April 27, 2011 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 Link to comment Share on other sites More sharing options...
