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

Which operation is performed first in the expression: 5 + 2 x 3?

Back

Multiplication (2 x 3 = 6, then 5 + 6 = 11).

Front

What is the first step in solving: 8 - (3 + 2) x 2?

Back

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

Front

In the expression 6 + 4 x 2, which operation do you perform first?

Back

Multiplication (4 x 2 = 8, then 6 + 8 = 14).

Front

What is the result of: 10 + 45 ÷ 9 - (14 ÷ 2)?

Back

8 (First, divide 45 by 9 to get 5, then divide 14 by 2 to get 7, then 10 + 5 - 7 = 8).

Front

Which operation is performed second in the expression: 44 ÷ 2 x (3 - 1)?

Back

Division (44 ÷ 2 = 22, then multiply by (3 - 1) = 2).

Front

What is the first step in solving: 3 + 4 x 6 - 4?

Back

Multiplication (4 x 6 = 24, then 3 + 24 - 4 = 23).

Front

What is the result of: (13 - 1) + 4?

Back

16 (First, subtract 1 from 13 to get 12, then add 4).

Front

What is the importance of parentheses in an expression?

Back

Parentheses indicate which operations should be performed first.
