Mathematics is the study of numbers, shapes and patterns. The word is sometimes shortened to maths (in England, Australia, Ireland, and New Zealand) or math (in the United States and Canada). Mathematics is useful for solving problems that occur in the real world, so many people besides mathematicians study and use mathematics. Today, some mathematics is needed in many jobs. Business, science, engineering, and construction need some knowledge of mathematics.
Mathematics solves problems by using logic. Mathematicians often use deduction. Deduction is a special way of thinking to discover and prove new truths using old truths. To a mathematician, the reason something is true is just as important as the fact that it is true. Using deduction is what makes mathematics thinking different from other kinds of thinking. Mathematics includes the study of:
- Numbers (example 3+6=9)
- Structure: how things are organized.
- Place: where things are and their arrangement.
- Change: how things become different.
Mathematics uses logic, paper, and calculator. These things are used to create general rules, which are an important part of mathematics. These rules leave out information that is not important so that a single rule can cover many situations. By finding general rules, mathematics solves many problems at the same time as these rules can be used on other problems.
A proof gives a reason why a rule in mathematics is correct. This is done by using certain other rules that everyone agrees are correct, which are called axioms. A rule that has a proof is sometimes called a theorem. Experts in mathematics perform research to create new theorems. Sometimes experts find an idea that they think is a theorem but cannot find a proof for it. That idea is called a conjecture, until a proof is found or it's proven to be incorrect.
Sometimes, mathematics finds and studies rules or ideas in the real world that we don't understand yet. Often in mathematics, ideas and rules are chosen because they are considered simple or neat. On the other hand, sometimes these ideas and rules are found in the real world after they are studied in mathematics; this has happened many times in the past. In general, studying the rules and ideas of mathematics can help us understand the world better.

- Some areas of mathematics study the structure that an object has.
- Some areas of mathematics study the shapes of things.
- Some areas of mathematics study the way things change.
- Applied mathematics uses mathematics to solve problems of other areas such as engineering, physics, and computing.

Foundations and methodsEdit
Progress in understanding the nature of mathematics also influences the way mathematicians study their subject.

History and the world of mathematiciansEdit
Mathematics in history, and the history of mathematics.
Often, the word "mathematics" is made shorter into maths (in British English) or math (in American English). The short words maths or math are often used for arithmetic, geometry or simple algebra by students and their schools.
