Got PEMDAS? Mastery Check 2021

The order of operations (PEMDAS) tells you...

• How many operations there are to use in math.

• How to solve exponential form problems.

• How to find partner operations for the main operations in math.

• How to solve multi-operation (x, /, +, -) equations in the correct sequence using given steps.

What is the correct set of steps to use in solving order of operations questions?

• participles, exclamations, main idea, antonyms, subjects

• parentheses, add/subtract, multiply/divide, exponents

• parentheses, exponents, multiply/divide, add/subtract

• penguin, eagle, mockingbird, dodo, albatros, seagull

Which step is first in the following:

6x3 + 5^2 - 4

(*5^2 means 5 squared)

• 6x3

• 5^2

• 2-4

• 3+5

Which step would come first:

5^3 - 6 x 5 - 4

(*5^3 means 5 cubed)

• 5^3

• 3-6

• 6x5

• 5-4

Which step should you work out first?

3^3 - 2 x (10 - 3)

(*3^3 is 3 cubed)

• 3^3

• 3-2

• 2 x 10

• (10-3)

Which operation would you work LAST?

16 - 2 + (4 x 8)

• x

• -

• +

• ( )

Simplify the expression.
