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 × 2

Back

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

Front

Calculate: (8 + 2) × 5

Back

50 (First, add 8 + 2 = 10, then multiply by 5).

Front

What operation should be performed first in the expression: 6 + 4 × 3?

Back

Multiplication (4 × 3 = 12, then add 6).

Front

Calculate: 12 ÷ 4 + 3 × 2

Back

9 (First, divide 12 ÷ 4 = 3, then multiply 3 × 2 = 6, and finally add 3 + 6).

Front

What is the result of: 5 × (2 + 3) - 4?

Back

21 (First, add 2 + 3 = 5, then multiply 5 × 5 = 25, and finally subtract 4).

Front

Calculate: 10 - 2^3 + 6

Back

10 (First, calculate 2^3 = 8, then 10 - 8 + 6 = 8).

Front

What is the first step in solving: 7 - (3 + 2) ÷ 5?

Back

Calculate the expression in parentheses (3 + 2 = 5).

Front

Calculate: 15 + 7 × 2 - 11 + 35

Back

53 (First, multiply 7 × 2 = 14, then add and subtract in order).
