Parts of An Expression

100

What is an example of a variable?

Any letter we use to show an unknown value

200

What is the difference between an expression and an equation?

An equation has an equal sign, an expression does not

300

In the expression 3x + 2, what is the coefficient?

3

400

What is the constant in the expression 4 + 2y?

4

500

What is the value of x in the expression 2x + 3?

Trick Question! We don't know, and we don't care, because it's an expression not an equation.

200

Simplify: 5y + 3 - 2y

3y + 3

300

Simplify: 2x + 3y + 2

Trick Question! This is already simplified. 

2x + 3y + 2

400

Simplify: 2x + 5x² - x² + 1

4x²+2x+1

500

How many terms will this expression have when fully simplified?

3w + 4x² - w + 6 - 2w + x²

There will be 2 terms left!

3w - w - 2w is 0

4x²+x² is 5x² 

There's nothing to combine with 6, so our simplified expression is:

5x² + 6
