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 x 2

Back

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

Front

Calculate: (8 + 2) x 5

Back

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

Front

What operation should be performed first in the expression: 6 + 2 x 3?

Back

Multiplication (2 x 3 = 6, then add 6).

Front

Calculate: 12 - 4 + 3

Back

11 (First subtract 4 from 12 = 8, then add 3).

Front

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

Back

21 (First calculate inside the parentheses: 3 + 2 = 5, then 5 x 5 = 25, and finally 25 - 4 = 21).

Front

Calculate: 20 ÷ 4 + 3 x 2

Back

11 (First divide 20 ÷ 4 = 5, then multiply 3 x 2 = 6, and finally add 5 + 6 = 11).

Front

What is the value of: 7 - (3 + 2) x 2?

Back

-3 (First calculate inside the parentheses: 3 + 2 = 5, then multiply 5 x 2 = 10, and finally 7 - 10 = -3).

Front

Calculate: 15 - 3 x (2 + 1)

Back

6 (First calculate inside the parentheses: 2 + 1 = 3, then multiply 3 x 3 = 9, and finally 15 - 9 = 6).
