For example you may want to prove that n 3 - n is divisible by 3 for all positive integers. Although there are more complicated ways to show this. Mathematical Induction is a special way of proving things. It has only 2 steps: Step 1. Show it is true for the first one Step 2. Show that if any one is true then the next one is true Then all are true Have you heard of the "Domino Effect"? Step 1. The first domino falls Step 2. When any domino falls, the next domino falls. A set is the mathematical model for a collection of different things; a set contains elements or members, which can be mathematical objects of any kind: numbers, symbols, points in space, lines, other geometrical shapes, variables, or even other sets. The set with no element is the empty set; a set with a single element is a singleton..
