48/2(9+3)

We do the parenthesis first

48/2(12) and then 48/24

And then we get 2

>> No.2861112

2

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

48/2 (9+3)
Distribute the 2
48/(18+6)
Add 18 + 6
48/24
Multiply the 4 and 8
32/24
Multiply the 2 and 4
32/8 = 4
Easy mode.

>> No.2861159

You are all wrong except for >>2861110 because you always calculate the parenthesis first, meaning 2(9+3) and then 2(12) and then 24 and then you get 48/24 which is 2.

go back to school, fools.

>> No.2861204

>>2861159
You always calculate what is INSIDE the parenthesis first. meaning you end up with 48/2*12 which can be rearranged in any order you want.

>> No.2861211

48/2(9+3)
distribute the 48/2
48/2(9) + 48/2(3)
multiply
432/2 + 144/2
divide
216+72
add them together to get
288

>> No.2861217

>>2861204
False, division isn't commutative.

>> No.2861221

48/2=24

Idiots all of you

>> No.2861222

>>2861204

No, if there is a number in front of the parenthesis, you calculate that as well. Everything that is related to the parenthesis.

mfw everyone knows how to do this, but a few people don't know they're getting trolled and think they're super smart for knowing the order of operations.
