There are many different kinds of numbers.

A whole number is any counting number. Numbers, like 1/2 or .75, that you use to describe a part of something are not whole numbers.

A positive number is a number greater than zero. It can be written with or without a + symbol in front of it. A gain in something is written with a positive number. Profit, increase, and income are all examples of words that mean positive.

A negative number is a number that is less than zero. It is always written with a - symbol in front of it. A loss is written with a negative number. Decrease, spend, and decline are examples of words that mean negative.

An integer is any positive whole number or its negative. Zero is also considered an integer.
