multiplication before division

i just asked my boy on fb who has a computer science degree dude said 2

safe to say aint no math geniuses in this bitch

 

[fiat_money]

so you interpret 48/2x as meaning (48/2)(x)?

I interpret 48/2(x) as (48/2)*(x), 48/2*(x) or just 48/2x, they all end up being 24x.

9+3 is 12, then divide 48 by 2 thats 24, then multiply 24 by 12 thats 288

 

[redhandedbandit]

trust google alright bruh its 2

 

[whatevathehell]

man I deleted all my posts cuz at first I got 288 then I was convinced it was 2 =, then young ice came with the google calculator and now this shit with redhandedbandit...i need to go back to school
its 2 though...multiplication takes precendence over division according to pemdas.

 

[major pain]

People coming up with 288 arent "solving" the Parentheses first.

In order to solve it you have to distribute the 2 first. So, 2(9+3) = 18+6 = 24

48/24 = 2

That's where you its different. Unless specifically stated then you shouldnt add the parentheses yourself.

 

[major pain]

the 2 isn't part of the brackets bro. It's outside the brackets.

I know... thats why I typed 2(9+3)...

You have to distribute first.

okay....damn I hate math

 

[JadaRoss]

very simple....288

It seems you're implying that multiplying 48/2 by x is somehow different than multiplying (48/2) by x or (48/2) by (x).

It isn't.

 

[major pain]

People. These are different problems

48/2(9+3) = 2

(48/2)(9+3) = 288

 

[stilldat_dude]

never have i been so proud and so ashamed at a thread at the same time....smh our school systems are really failing us

 

[ImGettingOld]

Its 2 google is wrong

 

[major pain]

exactly. and as such, you don't multiply the 2 with the 12 during brackets phase. you wait until multiply/divide phase

multiply and divide are really one phase of the solving process. You dont do them in order that they come in according to pedmas, you do them in order that you see them from left to right in the equation.

in the case of this equation, you'd divide 48 by 2, and then multiply it by 12.

You're interpreting it wrong.

The parentheses dont go away by adding 9+3.

It doesnt go away until there are no factors outside the parentheses. The 2 being there modifies whatever is in the parentheses. 48/2(12) = 48/24
