order of operations

Front

What is the order of operations in mathematics?

Back

The order of operations is a set of rules that determines the sequence in which calculations are performed. The acronym PEMDAS helps remember the order: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What does PEMDAS stand for?

Back

PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. It is a mnemonic to remember the order of operations.

Front

Calculate: 5 + 3 x 2

Back

11 (First, multiply 3 x 2 = 6, then add 5.)

Front

Calculate: (8 - 3) x 2 + 4

Back

14 (First, calculate inside the parentheses: 8 - 3 = 5, then multiply by 2 to get 10, and finally add 4.)

Front

What operation should be performed first in the expression: 12 + 4 x 2?

Back

Multiplication (4 x 2 = 8, then add 12.)

Front

Calculate: 7 + 2 x (3 + 1)

Back

15 (First, calculate inside the parentheses: 3 + 1 = 4, then multiply by 2 to get 8, and finally add 7.)

Front

What is the result of 10 - 2 x 3 + 5?

Back

19 (First, multiply 2 x 3 = 6, then perform subtraction: 10 - 6 = 4, and finally add 5.)

Front

Calculate: 6 + 2^3 - 4

Back

10 (First, calculate the exponent: 2^3 = 8, then add 6 to get 14, and finally subtract 4.)

Front

What is the value of 15 - (3 + 2) x 2?

Back

5 (First, calculate inside the parentheses: 3 + 2 = 5, then multiply by 2 to get 10, and finally subtract from 15.)

Front

What is the first step in solving the expression: 9 + 6 ÷ 2?

Back

Division (6 ÷ 2 = 3, then add 9.)
