9 - 3 x 2 = 12
9 -3 x 2 = 3
Give the correct order of operations.
Parenthesis, Multiplication/Division, Addition/Subtraction
3 + 6 x 4
27
(14 + 6) x (12 -4) -9

10÷5 x 2 = 1
10÷5 x 2 = 4
Which comes first multiplication or addition
multiplication
25 ÷ 5 -2

If I have addition and subtraction in my expression, I should move from ______ ___ _______.
left to right
20 ÷ (8-3) + 16
20
( 10 + 19 -5 ) x 2

The problem was 20 - 5 x 2 + 3. My answer was 33. What did I do wrong?
I did not multiply first. The answer should be 13.
Why is it important to know order of operations as a mathematician?
So that everyone is solving the problem in the same way
7 + 3 x (8 ÷ 4)
13
2 x ( 9 x 9 + 2) - 8
158
the sum of 9 and 3 divided by 3
