Order of Operations review

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. The order is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What does PEMDAS stand for?

Back

PEMDAS is an acronym for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction, which represents the order of operations.

Front

Simplify: 3 + 5 × 2

Back

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

Front

What operation should be performed first in the expression: 8 - 2 × 3?

Back

Multiplication (Perform 2 × 3 first, then subtract from 8.)

Front

Solve: (4 + 6) ÷ 2

Back

5 (First, add 4 + 6 = 10, then divide by 2.)

Front

What is the result of 2^3?

Back

8 (2 raised to the power of 3 equals 2 × 2 × 2.)

Front

Simplify: 10 - (3 + 2) × 2

Back

0 (First, calculate inside the parentheses: 3 + 2 = 5, then multiply by 2: 5 × 2 = 10, finally subtract from 10.)

Front

What is the second step in the expression: 5 + 2 × 3 - 1?

Back

Multiplication (Perform 2 × 3 first, then proceed with addition and subtraction.)

Front

Solve: 6 ÷ 2 + 3 × 4

Back

15 (First, divide 6 ÷ 2 = 3, then multiply 3 × 4 = 12, finally add: 3 + 12 = 15.)

Front

What is the value of 5 - 3 + 2?

Back

4 (Perform subtraction and addition from left to right.)
