What acronym do we use to help us remember the order of operations?
BEDMAS
9 - 3 x 2=12
Correct answer is 3. Do x then -, not - then x.

23
14 - 2 x 7

How many students are in the 6th grade at our school?
51
Why are order of operations important for mathematicians?
So everyone can solve every problem the same (correct) way.
5 + 1 x 5 = 30
multiplication needs to be done before addition
1 x 5 = 5
5 x 5 = 25
7 + (2 x 4) - 1
14
49 ÷ (3+4) x 5

What are the order of operations?
Brackets, Exponents, Multiplication OR Division, Addition OR Subtraction
11 - 3 x 3 +1 = 22
11 - 9 + 1
2 + 1 = 3
56 ÷ (4+4) + 3
10
5 + 14 ÷ 2 × 5

How many siblings does Mr. Parkinson have?
What should I solve first? Addition or Subtraction?
15 - 2 + 8
Why?
Subtraction because even though it is listed after Addition in the order of operations we solve addition and subtraction questions in the order they occur from left to right.
4 + 5 + 7 - 3 x 2 = 26
You need to follow BEMDAS and do x first. Correct answer is 10.
20 – (5+3) x 2 + 4
8
(4 - 1) + (5 x 1) + 9

The problem was 20 - 5 x 2 + 3. My answer was 33. What did I do wrong?
I went from left to right without using the correct order of operations.
10 x 3 + (2 x 8) = 190
Follow BEDMAS
multiplication comes before addition
(5 x 4) – 6 ÷ 2 + 9
26
2 x (3 x 5) + 10 - 5
