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 x 2 x 2.

Front

What is the first step in the Order of Operations?

Back

The first step is to solve any expressions inside parentheses.

Front

What is the second step in the Order of Operations?

Back

The second step is to evaluate exponents.

Front

What is the third step in the Order of Operations?

Back

The third step is to perform multiplication and division from left to right.

Front

What is the fourth step in the Order of Operations?

Back

The fourth step is to perform addition and subtraction from left to right.
