What happens when you have 2 operations that are "tied" such as multiplication and subtraction? How do you decide which to do first?
You solve them LEFT to RIGHT
10 ÷ 2 + 3
12 ÷ (8 − 2) x 6
12

44
Solve the problem.
5 + 8 ÷ 4 (3 x 10) - 2
63
Why do we need the Order of Operations?
To have shared way for all Mathmaticians to solve problems that is agreed upon.
(40 - 20) x 6 ÷ 2
60
3 × 6 + (5 - 4) + 6 ÷ 2
22
