Mathematics (also called math or maths) is the art of using numbers to determine other numbers, primarily based on 4 operations.

## Contents

Addition is putting two numbers together. We will use both normal numbers (yes, I know what it is called but I don't want to be too technical) and unary (a numeral system that only uses 1s and there are as many ones as the number says.) An example:

11111 (5) + 11 (2) = 1111111

This operator is useful for putting things together. Here is a real-life scenario:

You have three apples and your friend has six. You want to give your friend your three apples. How many apples will your friend have now?

## Subtraction

Subtraction is the opposite (inverse) of addition. We will use the same type of example.

Unary: 1111 - 1 = 111

Word Problem: You and your big brother have candies. You have three candies and your brother takes two away from you. How many candies do you have?

## Multiplication

This is a slightly more complicated operation because it involves repeated addition. (There is another operator called exponents, but let's not go there.) Multiplication is the addition operator being iterated. More formally, this means that you take a number a and add it to itself b times. Here is an example: 3 * 4 = 12

## Division

This is the inverse of multiplication. It is defined as the number of times that a number has to be subtracted to get to less than the number. Here is an example: 6 / 3 = 2.

## Republicans and maths

It is widely known that Republicans are immune to math. In the hands of a Republican, 32% may be a strong approval rating and the Internet may fit into a single e-mail. Current theories have it that Republicans have gained this remarkable ability to ignore the laws of reality by playing so much golf, in which the lowest score wins and from reading the Bible where maths doesn't add up.
