Algebra is a branch of mathematics that uses letters or other symbols to represent unknown quantities, called variables. These variables and number values are combined to form equations.
The rules of these equations follow the same rules as arithmetic, such as the laws for addition and multiplication.

This category lists pages and sites that deal with the basic mathematical operations of addition, subtraction, multiplication, and division. It includes games, tutorials, online drills, and printable worksheets.

Counting is the method of naming "whole" numbers, in order, from a smaller number to a larger one. It is an essential part of math to be able to know the number names and understand what they mean, similar to reciting the letters of the alphabet.

Numbers have four ways of being represented. For example the number 3 can be recognised as

• a) 3
• b) three
• c) III
• d) speaking the word "three"

Knowing how to read and understand what numbers mean helps with telling time, counting money, reading street signs or even helping set the table.

Formulas are used in many subjects, to work out the answers to problems, or to find an unknown factor.

Graphs can be used to solve problems or to illustrate relationships between variables.

Mathematics has been around since the development of written language and probably before that. The field of working with numbers and formulas first came from practical uses such as counting crops, measuring land, astronomical data for sailing, and trading in the market square.

The field of math, in its many forms, has developed in all parts of the world from the Mayans to the Mexican region to Africa and Europe and China. As more texts are found and translated, it will be very exciting to see what we will find.

Important developments in math includes counting, writing of numbers, calculating amounts, working with fractions, creating a number system, using variables, using graphs and applying these ideas to the real world.
