WHAT TYPES OF NUMBERS ARE THERE?

Abstract

The first mathematical thing we learn to do in our lives is count — that is, we learn about the integers 1,2,3,4,5, etc. These numbers are also called the natural numbers. They go on forever: no matter how large a number you have reached, you can always add 1 to get an even larger number. You can visualise the natural numbers as lying along a ruler that is infinitely long, each natural number a distance of 1 from the previous one.
