# Mini-Quiz: Terminology Used in Algebra

by Ron Kurtus (revised 17 August 2012)

Take this Mini-Quiz to check your understanding of the lesson material.

1. What could x represent?

It could only represent a whole number

It could only represent a real object

2. Why is xyz used in algebra to denote multiplication instead of x*y*z?

xyz should not be used because it might create confusion with x + y + z

It is just easier to write and avoids all the * characters

They mean completely different things

3. Is 3x + 7y = 0 an expression?

Yes

It is undefined because it includes 0

No, it is an equation

If you got all three correct, you are on your way to becoming a Champion in Algebra. If you had problems, you had better look over the material again.
