We all work with numbers every day, often without really thinking about them: numbers on the newspaper (prices, dates,amounts); numbers on the television or radio; sporting results; time; labels on food; money; addresses, bar codes and many more.

The following diagram shows the relationship between the types of numbers. Scroll down the page for more examples and solutions on types of numbers.

- Natural numbers are positive integers. E.g. 1, 2, 3, …

- Some authors take whole numbers to be 0, 1, 2, 3, …
- Other authors may consider whole numbers as

... –4, –3, –2, –1, 0, 1, 2, 3, 4, ...

which makes whole numbers the same as integers.

- Rational numbers are numbers that can be written as a fraction where the numerator and denominator are integers.

- Irrational numbers are numbers that are not rational. In other words, they are numbers that cannot be written as fractions.
- In decimal form, these numbers go on forever and the same pattern of digits are not repeated.
- For example:. pi(π) = 3.142.. and √2 = 1.4142….

- Real numbers are all the rational and irrational numbers.

This video explains the different classifications of Real Numbers and has a number of examples. The following video will describe what are natural numbers, integers, rational numbers and more.

- The square of a number is the number multiplied by itself.
- For e.g. square of 4 = 4 2 = (4 × 4) = 16
**Perfect squares**are squares of whole numbers.- Some examples of perfect squares are 1
^{2}= 1, 2^{2}= 4, 3^{2}= 9, 4^{2}= 16, 5^{2}= 25, 6^{2}= 36

- The square root of a number
*n*is the number that gives*n*when multiplied by itself. - For e.g. square root of 49 = 7 because (7 × 7) = 49
- The square root of a perfect square would be a whole number.

- The cube of a number is the number multiplied by itself twice
- For e.g. cube of 4 = 4 3 = (4 × 4 × 4) = 64
**Perfect cubes**are cubes of whole numbers.- Some examples of cubes are 1
^{3}= 1, 2^{3}= 8, 3^{3}= 27, 4^{3}= 64, 5^{3}= 125, 6^{3}= 216

- The cube root of a number
*n*is the number that gives*n*when multiplied by itself twice**.** - For e.g. cube root of 27 = 3 because (3 × 3 × 3) = 27
- The cube root of a perfect cube would be a whole number.
