Order of Operations and More

Front

What is the Order of Operations?

Back

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).

What does the term 'Exponent' mean?

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: 8 + 2 x 5

Back

18 (First, multiply 2 x 5 = 10, then add 8).

Front

What is the Greatest Common Factor (GCF)?

Back

The largest number that divides two or more numbers without leaving a remainder.

Front

Find the GCF of 24 and 36.

Back

12 (The factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24; the factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, 36. The greatest common factor is 12).

Front

What does (3 + 5)^2 equal?

Back

64 (First, add 3 + 5 = 8, then square it: 8 x 8 = 64).

Front

Calculate: 10 - 2^3 + 4

Back

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

Front

What is the result of 5 x (2 + 3)?

Back

25 (First, add 2 + 3 = 5, then multiply 5 x 5 = 25).

Front

What does 4^3 mean?

Back

4 x 4 x 4 (4 multiplied by itself three times).

Front

Calculate: 6 + 2 x (3 + 1)

Back

14 (First, calculate inside the parentheses: 3 + 1 = 4, then 2 x 4 = 8, and finally 6 + 8 = 14).
