SOL 5.7 Order of Operations Pre-Test

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).

Front

What does the term 'exponent' mean?

Back

An exponent is a number that shows how many times a base is multiplied by itself. For example, in 10², 10 is the base and 2 is the exponent.

Front

What is the first step in the Order of Operations?

Back

The first step is to solve expressions inside parentheses.

Front

Simplify: 3 + 5 × 2

Back

13 (First, multiply 5 × 2 = 10, then add 3 + 10 = 13).

Front

What is the result of 8 - 3 × 2 + 4?

Back

The result is 9 (First, multiply 3 × 2 = 6, then 8 - 6 + 4 = 6).

Front

What is the second operation performed in 6 ÷ 2 - 2 × (7-2)?

Back

6 ÷ 2 (The first operation is solving the parentheses, then division).

Front

What does 'simplify' mean in mathematics?

Back

To reduce an expression to its simplest form by performing operations and combining like terms.

Front

What is the value of 5²?

Back

25 (5 multiplied by itself, 5 × 5).

Front

What is the result of 16 - (4 × 2)?

Back

8 (First, calculate inside the parentheses: 4 × 2 = 8, then 16 - 8 = 8).

Front

What is the result of 61 + 4 × (5 + 10) ÷ 5?

Back

67 (First, calculate inside the parentheses: 5 + 10 = 15, then 4 × 15 = 60, then 60 ÷ 5 = 12, finally 61 + 12 = 73).
