order of operations

Front

What is the order of operations?

Back

The order of operations is a set of rules that determines the sequence in which calculations are performed in a mathematical expression. The common acronym to remember this is PEMDAS: 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: P - Parentheses, E - Exponents, MD - Multiplication and Division (from left to right), AS - Addition and Subtraction (from left to right).

Front

What operation should be performed first in the expression 5 + 3 x 2?

Back

Multiplication should be performed first, so the expression becomes 5 + 6 = 11.

Front

In the expression 8 - (3 + 2), what should you calculate first?

Back

You should calculate the expression inside the parentheses first: 3 + 2 = 5, then 8 - 5 = 3.

Front

What is the result of 6 + (4 x 3)?

Back

The result is 6 + 12 = 18.

Front

Which operation is performed second in the expression 38 + (9 x 6) ÷ 3?

Back

The second operation performed is division.

Front

What is the value of 2 + (9^2 - 4)?

Back

The value is 2 + (81 - 4) = 2 + 77 = 79.

Front

In the expression 10 - 4 ÷ 1 x 5, which operation is done first?

Back

Division is done first.

Front

What is the result of 5 - 3 + 2?

Back

The result is 5 - 3 = 2, then 2 + 2 = 4.

Front

What is the importance of parentheses in mathematical expressions?

Back

Parentheses indicate which operations should be performed first, helping to clarify the order of calculations.
