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

Solve: 3 + 5 x 2

Back

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

Front

Solve: (6 + 2) x 3

Back

24 (First, add 6 + 2 = 8, then multiply by 3.)

Front

What is the first step in the Order of Operations?

Back

Perform calculations inside Parentheses.

Front

Solve: 10 - (2 + 3) x 2

Back

0 (First, calculate inside parentheses: 2 + 3 = 5, then multiply: 5 x 2 = 10, finally subtract: 10 - 10 = 0.)

Front

What is the result of 8 ÷ 4 + 2?

Back

4 (First, divide 8 ÷ 4 = 2, then add 2.)

Front

Solve: 15 - 3 x 4 + 2

Back

5 (First, multiply: 3 x 4 = 12, then subtract: 15 - 12 = 3, finally add: 3 + 2 = 5.)

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

Solve: (5 + 3) x (2 + 2)

Back

32 (First, calculate inside parentheses: 5 + 3 = 8 and 2 + 2 = 4, then multiply: 8 x 4 = 32.)
