What are the Steps
What is the first step in the order of operations?
Parentheses
Solve: 3 + 5 × 2
13 (5 × 2 = 10, then 3 + 10 = 13)
What do parentheses indicate in a math expression?
They indicate which operations to perform first.
What does an exponent mean?
It tells you how many times to multiply a number
What comes after parentheses in the order of operations?
Exponents
Solve: (6 + 4) × 2
20 (6 + 4 = 10, then 10 × 2 = 20)
Give an example of a problem using parentheses.
Let's see what you came up with
Solve: 32
9 (3 × 3 = 9)
What is the third step in the order of operations?
multiplication and division from left to right
Solve: 8 + 23
16 (23 = 8, then 8 + 8 = 16)
What comes first, exponents or parentheses?
parentheses
What is 23?
8 (2 × 2 × 2 = 8)
What is the last step in the order of operations?
Addition and subtraction from left to right
Solve: 12 ÷ 4 + 3
6 (12 ÷ 4 = 3, then 3 + 3 = 6)
True or False: You can ignore parentheses if they are present.
False
How would you write 4 × 4 × 4 using exponents?
43
Name the acronym that helps remember the order of operations.
PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction
Solve: (5 + 3) × (2 + 2)
32 ((5 + 3 = 8) and (2 + 2 = 4), then 8 × 4 = 32).
What is the result of: 5 + (2 × 3)?
11 (2 × 3 = 6, then 5 + 6 = 11)
Solve: 5 + 24.
21 (24 = 16, then 5 + 16 = 21)
