FLASHCARD: Order of Operations with Exponents

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 acronym PEMDAS is often used: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Identify the error: 6 + 3 - 2 = 6 - 2 = 4

Back

There is a subtraction error.

What is an exponent?

Back

An exponent is a number that indicates how many times to multiply a base number by itself. For example, in 3², 3 is the base and 2 is the exponent, meaning 3 is multiplied by itself 2 times (3 x 3).
