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

What operation do you perform first in the expression: 3 + 4 × 2?

Back

Multiplication (4 × 2 = 8), then Addition (3 + 8 = 11).

Front

Evaluate: 8 - 3 + 2.

Back

7 (Perform subtraction first: 8 - 3 = 5, then add 2: 5 + 2 = 7).

Front

Evaluate: (5 + 3) × 2.

Back

16 (Perform the operation inside the parentheses first: 5 + 3 = 8, then multiply: 8 × 2 = 16).

Front

What is the result of 10 ÷ 2 × 5?

Back

25 (Perform division and multiplication from left to right: 10 ÷ 2 = 5, then 5 × 5 = 25).

Front

Evaluate: 6 + (2 × 3).

Back

12 (Perform the operation inside the parentheses first: 2 × 3 = 6, then add: 6 + 6 = 12).

Front

What is the first step in solving: 12 - (4 + 2)?

Back

Calculate the expression inside the parentheses first: 4 + 2 = 6.

Front

Evaluate: 15 - 3 × (2 + 1).

Back

6 (Calculate inside the parentheses first: 2 + 1 = 3, then multiply: 3 × 3 = 9, finally subtract: 15 - 9 = 6).

Front

What is the result of (8 - 3) × 2 + 1?

Back

11 (Calculate inside the parentheses first: 8 - 3 = 5, then multiply: 5 × 2 = 10, finally add: 10 + 1 = 11).
