What is the answer to this question?
48÷2(9+3)=
( If I do it with PEMDAS, the answer would be 2, but when I type in google, it give me 288)
[ 9+3 = 12 -> 48/2(12) -> 2 x 12 = 24 -> 48/24 = 2]
48÷2(9+3)=

Google is right!
PEMDAS works like this:
1. Parentheses
2. Exponential
3. Multiplications and Divisions
4. Additions and subtractions.
BUT when multiplications and divisions are both present without parentheses, they are executed from <i>left to right</i>.
The same rule applies when we have additions and subtractions.
So
48÷2(9+3)
=48÷2*12
=24*12
=288
Compare with
6-2+3
=4+3
=7
