- a Any number that can be expressed as the ratio of two integers, a/b, where b can not equal zero.
- b An equation that states that two ratios are equal
- c An expression that contains at least one variable
- d For all rational numbers a, b, and c, if a = b, then ac = bc

5 Multiple choice questions
- For any rational number a, -1 * a = -a.
- An expression is that is written with exponents.
- This is a number's distance from zero on a number line. Distance is always positive.
- For any number a, a + 0 = a and 0 + a = a.
- For any numbers a, b, and c, a(b + c) = ab + ac.
For any numbers a, b, and c, (b + c)a = ba +ca
5 True/False questions
The inverse of a sum property → AKA Subtracting Numbers. For all rational numbers a and b, a - b = a + (-b)
Property of Multiplicative Inverse → For each rational number a, there is one and only one rational number -a such that a + (-a) = 0
Ratio → A comparison of two quantities, often expressed as a fraction
Property of additive inverses → For each nonzero rational number a, there is one and only one rational number 1/a such that a * 1/a = 1. AKA: reciprocal
Commutative property of multiplication → For any number a and b,
a * b= b * a
