In the expression 3 * (2 + 4) - 1, what is the correct first step?

If an expression includes both multiplication and division, which should be done first?

• Neither, exponents come first

• Multiplication

• Both at the same time, working from left to right

When solving problems with multiple parentheses, how should you proceed?

• Ignore parentheses and solve exponents first

• Solve from left to right

• Solve from right to left

• Solve the innermost parentheses first

• 25

• 15

• 20

12 - 4 x 2 = 

• 16
• 4
• 8
• 18

18 + (6 – 2) × 2 =

• 26
• 29
• 44
• 40

What would be my first step? 3 + 4 x 6 - 4 =

• addition
• multiplication
• subtraction
• exponents

2 + (9² - 4)

• 16
• 77
• 79
