Why does 2 x 2 = 4? Why does -3 + 5 = 2? Have you ever thought in depth about what numbers are? Numbers are often thought of as a boring part of a Maths class; this application will show that they can be fun and when their true nature is understood they are very fascinating.
How Numbers Works explains how numbers are constructed and how they work via animations.
First the construction of the natural numbers (or counting numbers) is explained. Following those come the integers, which enhance the natural numbers with the possibility of subtraction, and finally come the quotients (or fractions) which allow for division.
