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 solving: 5 + 2 x (3 - 1)?

Back

Evaluate the expression inside the parentheses: (3 - 1) = 2.

Front

Solve: 10 - 4 + 2

Back

8 (Perform subtraction first, then addition).

Front

What is the second step in solving: 8 ÷ 2 + 3 x 4?

Back

Perform the multiplication: 3 x 4 = 12.

Front

Solve: 2 + 3 x 4 - 5

Back

9 (First, multiply 3 x 4 = 12, then add 2 and subtract 5).

Front

Identify the error: 7 - 2 + 3 = 8

Back

The error is in the order of operations; subtraction should be done first.

Front

Solve: (5 + 3) x (2 - 1)

Back

8 (First, evaluate inside the parentheses: 5 + 3 = 8 and 2 - 1 = 1, then multiply).
