It's been on the web since a while 48÷2(9+3)=?
Looking to start a fight? :P
Lets start a discussion with embasement! hahaha
I'll agree with @sarah43 on this one. Wait for the haters :P
loll. haters gonna hate :)
but that means multiplication has priority over division. Is that algorithmically right?
|dw:1343445503313:dw| just type it in google....itll solve it
paranthesis first |dw:1343445601763:dw| |dw:1343445645556:dw|
oh sry error in calculation xD ur right sara
but it could be parenthesis first, then division, then multiplication. (3+9)=12 48/2=24 24*12=288
It all boils down to whether you think a÷b(c + d) = a÷(bc + bd) or = (a/b)(c+d) In other words, if you treat this division as a fraction, is (9+3) in the numerator or denominator?
no u cannot do 48/2 cuz u have to distribute the 2 first. i made a mistake like this b4 and this is what the teacher told me. the 2 has to be distributed so u have 2*12=24 THEN divide by 48 to get 2
but which one is correct according to mathematics? or both answers are?
u have to use PEMDAS order of operations Paranthesis Exponents Multiplication Division Addition Subtration mulitplication comes first so according to the rules of operations that is what u would do
So that's a convention? (PEMDAS)
Let's boil it down... Since (9+3) is enclosed in parentheses, they are but one term. Therefore, let x = (9+3) Then your expression becomes 48÷2x Since 2x = 2(9+3) = 24, 48÷2x = 48÷24 = 2 There :)
My friend told me the right answer is 288. He went trough that discussion, but came up with the idea of testing the problem on machines, since they need to follow a convention (that was his way of thinking). When I asked him, he was like "obviously it is 288!" And indeed, even google says it is 288. . ., because u need to see 48/2 as one number, and (3+9) as another (numerator). Or, in other way, multiplication has the same priority as division, so in the case of this problem, u just solve from left to right. Remembering there's no difference in doing (+) first or (-) first when you have an basic equation, such as a+b-c-d+e (just to say + has no priority over -). What do you think?
