Rules for subtracting real numbers:
1. a  b = a + (b)
2. a  (b) = a + b
To subtract b, you add the opposite of b.
Example 1:
Subtract 3  5.
3  5 = 3 + (5) = 8.
Note: Subtracting 5 is the same as adding a 5.
Example 2:
Subtract 3  (5).
3  (5) = 3 + 5 = 2.
Note: Subtracting 5 is the same as adding 5.
