Integer Size

Question:
Our maximum int value is 32,768, but our minimum int value is -32,767. Why aren't they the same?

Answer:
Because a short integer (2 bytes or 16 bits) can hold any of 65,536 possible values. That's 32,768 times two. But one of those possible values is needed to represent 0. It had to be taken from a possible negative or possible positive value, and it was apparently taken off the negative side.
