- For all rational numbers a, b, and c, if a = b, then ac = bc
- Replace each variable in the expression by a given value and simplify that result.
- For each nonzero rational number a, there is one and only one rational number 1/a such that a * 1/a = 1. AKA: reciprocal
- For any number a,b and c,
a + (b + c)= (a + b) + c

5 True/False questions
Rational number → Any number that can be expressed as the ratio of two integers, a/b, where b can not equal zero.
Exponential notation → An expression is that is written with exponents.
Variable → Replace each variable in the expression by a given value and simplify that result.
Multiplicative Identity → For any number a, 1 * a = a and a *1 = a.
The inverse of a sum property → For any rational number a and b, -(a + b) = -a + (-b)
