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 should be performed first in the expression 4 + 9 + 8 ÷ 4?

Back

Division should be performed first, so calculate 8 ÷ 4 = 2, then add 4 + 9 + 2 = 15.

Front

True or False: Multiplication comes before addition in the Order of Operations.

Back

True.

Front

In the expression 23 + (30 ÷ 10) x 4, what operation is done first?

Back

Division is done first: 30 ÷ 10 = 3.

Front

What is the result of the expression 8 + 2 ⋅ 7?

Back

The result is 22, as multiplication is done before addition: 2 ⋅ 7 = 14, then 8 + 14 = 22.

Front

Which operation comes first in the expression 10 - 4 ÷ 1 x 5?

Back

Division comes first: 4 ÷ 1 = 4, then multiply by 5.

Front

What is the result of 5 + 3 x 2?

Back

The result is 11, as multiplication is done first: 3 x 2 = 6, then 5 + 6 = 11.

Front

What is the importance of parentheses in mathematical expressions?

Back

Parentheses indicate which operations should be performed first, overriding the usual order of operations.

Front

If an expression has both addition and subtraction, which do you perform first?

Back

You perform them from left to right, as they are of equal precedence.
