Chapter 3.4 - Subtracting Integers
Adding and subtracting integers are closely related.
Subtracting is the same as adding the opposite. In other words...
5 - 3 is the same as 5 + (-3). Either way, the answer is 2.
This is an important concept to understand. To help us remember, we sometimes use the phrase "chop-chop." We change the subtraction sign to addition with our first chop, and then change the sign of the second number with our second chop.

Character vs. Reputation
Be more concerned with your character than your reputation.
Character is what you really are.
Reputation is what people say you are.
-John Wooden
