== Complex Numbers == <br />
Complex numbers are numbers which have a real part and an imaginary part, usually written in the from a + b<math>i</math>.<br />
=== Real Numbers ===<br />
Real numbers is the set of all numbers which aren't imaginary, eg. don't have the b<math>i</math> counterpart and can be squared into some nonnegative number.<br />
=== Imaginary Numbers ===<br />
[[Imaginary numbers]] is the set of numbers which do have the b<math>i</math> counterpart. They will always be squared into a negative number.<br />
== Set of all Real Numbers == <br />
The set of all real numbers can be classified into two major sub sets, the set of irrational and rational numbers.<br />
=== Irrational Numbers ===<br />
Irrational numbers are all numbers which cannot be simplified into the from a/b where b isn't 0.<br />
=== Rational Numbers ===<br />
Rational numbers are all numbers which can be simplified into a/b. The rational numbers can be further split into to more subsets, subsubsets, and so on.<br />
== Set of Real Numbers ==<br />
=== Integers ===<br />
Integers are all numbers which aren't fractions but can be simplified into a/b. For example, 2 is an integer and 2/3 isn't. Usually integers are numbers we use for our daily counting. They are both negative and nonnegative.<br />
=== Natural Numbers ===<br />
Natural numbers are all positive integers. Examples are 2 and 3. 0 is nonnegative, but isn't positive so is therefore excluded. Natural numbers are a subset of integers, which are a subset of rational numbers, which combine with irrational numbers to make real numbers, which combine with imaginary numbers to make the set of all complex numbers.</div>Krishkhushi09
