Order of Operations - 5th grade

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

Simplify: 3 + 5 x 2

Back

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

Front

Simplify: 10 - 2 x 3 + 4

Back

8 (First, multiply 2 x 3 = 6, then 10 - 6 + 4 = 8.)

Front

What do parentheses indicate in an expression?

Back

They indicate that the operations inside them should be performed first.

Front

Simplify: 4 x (2 + 3)

Back

20 (First, add 2 + 3 = 5, then multiply 4 x 5 = 20.)

Front

What is the result of 6 + 2 x 3?

Back

12 (First, multiply 2 x 3 = 6, then add 6 + 6 = 12.)

Front

Simplify: (8 - 3) x 2 + 1

Back

11 (First, subtract 8 - 3 = 5, then multiply 5 x 2 = 10, and finally add 1.)

Front

What is the importance of the Order of Operations?

Back

It ensures that everyone calculates expressions in the same way, leading to consistent results.

Front

Simplify: 5 + (3 x 2) - 4

Back

7 (First, multiply 3 x 2 = 6, then 5 + 6 - 4 = 7.)
