What Are Math Expressions? Math expression is defined as a way to express a question in mathematical terms. This is where we use variables and numbers to identify a problem. Now, a variable is an alphabet we use to represent an unknown number. Let us consider an example. 12 + x = 16, We have to find the unknown x of this expression. Now, in order to find out the unknown here, we can just subtract 12 on both sides of the equal sign. 12 + x - 12 = 16 - 12, On the left side, 12 – 12 will be cancelled out and become zero. While on the right side, 12 will be subtracted from 16 to get an answer 4 from it. The resultant expression becomes x=4, The expression above means that the unknown variable x is 4.

#### Homework Sheets

The first two are the standard problems that you will see for this standard. The third sheet I thought on for some time.

- Homework 1 - What is the volume and area of a cube with sides that measure 12/3 feet?
- Homework 2 - The volume of a cube can be expressed as: volume = (length of sides)cubed
- Homework 3 - The area of a cube can be expressed as: area = 6 (length of sides)squared.

#### Practice Worksheets

Each sheet starts with word problems and then moves to just basic problems.

- Practice 1 - David has 9 more shirts than the James. James has s shirts. Write the expression that shows how many shirts David has?
