The properties of real numbers should be familiar to you. If the letters confuse you, try to plug in some actual numbers. Then it should be clear.
Example:
Reflexive Property
a = a
2 = 2
(a here means any real number, and what is true for 2 is true for all numbers)
DO:
- Set 1: #1-6, 20-23
- Set II: #24-26, 35-40
