Order of Operations

Front

What is the Order of Operations?

Back

A set of rules that determines the sequence in which calculations are performed in a mathematical expression.

Front

What does PEMDAS stand for?

Back

Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Front

Calculate: 3 + 5 x 2

Back

13 (First multiply 5 x 2 = 10, then add 3)

Front

Calculate: (8 - 3) x 2

Back

10 (First subtract 8 - 3 = 5, then multiply by 2)

Front

Which operation do you perform first in 6 + 2 x 3?

Back

Multiplication (2 x 3 = 6, then add 6 + 6 = 12)

Front

What is the result of 10 - 4 ÷ 2?

Back

8 (First divide 4 ÷ 2 = 2, then subtract 10 - 2 = 8)

Front

In the expression 5 + 3 - 2, which operation comes first?

Back

Depends (Addition and subtraction are performed from left to right.)

Front

Calculate: 7 x (2 + 3)

Back

35 (First add 2 + 3 = 5, then multiply by 7)

Front

What is the volume of a rectangular prism with length 5, width 3, and height 2?

Back

30 cubic units (Volume = length x width x height = 5 x 3 x 2)

Front

What is the result of 4 x 5 ÷ 2 - 1?

Back

9 (First multiply 4 x 5 = 20, then divide by 2 = 10, then subtract 1 = 9)
