What is the Order of Operations?

Back

The Order of Operations is a set of rules that tells us the correct sequence to evaluate a mathematical expression. The order is: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What does 'Parentheses' mean in the Order of Operations?

Back

Parentheses are symbols used to group parts of a mathematical expression. Operations inside parentheses should be performed first.

Front

What does 'Exponents' mean in the Order of Operations?

Back

Exponents indicate how many times a number (the base) is multiplied by itself. For example, 2^3 means 2 × 2 × 2.

What is the first step in solving 5 + (3 × 2)?

Back

The first step is to solve the expression inside the parentheses: 3 × 2 = 6.

What is the difference between Addition and Subtraction?

Back

Addition is the process of finding the total or sum by combining numbers, while Subtraction is the process of finding the difference by taking one number away from another.

What is the difference between Multiplication and Division?

Back

Multiplication is the process of adding a number to itself a certain number of times, while Division is the process of splitting a number into equal parts.
