48÷2(9+3) = ?

[hideinlight]

using BODMAS:

48 / 2 * (9+3) =
(9+3) = 12
2 * (12) = 24
48 / 24 = 2

2

To prove that the answer is 2, you must also prove that it's impossible to write 48÷2(9+3) as:
48 / 2 * (9+3) = 48 / 2 * 12

From the link:

Otherwise just go left to right. Example:

Right:
30 ÷ 5 × 3 = 6 × 3 = 18

Wrong
30 ÷ 5 × 3 = 30 ÷ 15 = 2

Can't believe how many people are still saying 2.

Can't believe how many people are still saying 2.

Indeed, I can't believe how many people discard the division and throw it in for kicks later.

48÷2(9+3) =

= 288

48/(2(9+3)) =

= 2

48÷2(9+3) =

= 288

48/(2(9+3)) =

= 2

The sad part is how many times it's been said that division and multiplication don't take precedence over eachother, and in the case where there is both you work from left to right.

Oh well, at least I passed the maths I had at school and varsity

All my calculators say 2 so answer is 2

 

[Keepa34]

48/2 * (9+3)
=> 24* 12
=> 288...

I tried ignoring this thread, but I ran out of intl, so I'm bored.

Implicit division or multiplication is ALWAYS done before implied division or multiplication. Division and multiplication go from right to left. The answer will be 288. Also, inputting it into my Sharp scientific calculator thus: 48/2(9+3) gives me 288. TBH, the only way I've divided since Gr. 9 is the fraction button. The division button gets a bit lonely sometimes so I divide with it to make it happy...

Yeah

So anyone going to post a new one?

[Duke Dude]

Lo, I thought the answer was 288 but then when I went back in time to what I learned I'm sure the answer is 2...
My scientific calculator says it's 2 as well...

As Lync said; BODMAS

How the heck does that work ^?

My maths skills seem very rusty.

..... Einstein... Where are you when we need you..

 

[shadowfox]

Can't believe this is still going.

As a note of interest, did you know that Einstein once failed maths?

It's 2.
Lets simplify.
Lets say (9+3) = x
Then we have
48
---
2x
Then we substitute x back in
48
--- = 2
24
Easy ... Go back to school 288's.

In the third line, he multiplies the left hand side with 4 throughout, but the right hand side with 5. Can't do that. Universe asplode.

Just as easily as it could be:

Lets say (9+3) = x
Then we have
48
-- x
2
Then we substitute x back in
24*12= 288

Easy ... Go back to school 2's.

o but he doesn't...he just simplifies the second line:

saying 16 = 4(squared)
36 = 4*9
25 = 5(squared)
45 = 9*5
