SF- 6S- 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 order is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). Often remembered by the acronym PEMDAS.

Front

What does an exponent represent?

Back

An exponent indicates how many times a number (the base) is multiplied by itself. For example, 3^2 means 3 x 3.

Front

Calculate: 2 + 3 x 4

Back

14 (First, multiply 3 x 4 = 12, then add 2.)

Front

Calculate: (5 + 3) x 2

Back

16 (First, add 5 + 3 = 8, then multiply by 2.)

Front

What is 4 x 4 x 4 x 4 x 4 written as an exponent?

Back

4^5 (This means 4 is multiplied by itself 5 times.)

Front

Calculate: 10 - 2^3 + 4

Back

10 (First, calculate 2^3 = 8, then 10 - 8 + 4 = 6.)

Front

What is the value of 6^3?

Back

216 (6 x 6 x 6 = 216.)

Front

Calculate: 3 x 2^2 + 24 ÷ 8

Back

15 (First, calculate 2^2 = 4, then 3 x 4 = 12, and 24 ÷ 8 = 3. Finally, 12 + 3 = 15.)

Front

What is another way to write 5^4?

Back

5 x 5 x 5 x 5 (This means 5 is multiplied by itself 4 times.)

Front

Calculate: 25 x 2 - 7

Back

43 (First, calculate 25 x 2 = 50, then 50 - 7 = 43.)
