**Mathematics**

The study of numbers, patterns, space, and change.

**Number.**

A number is a count or measurement.

They are really an idea in our minds. We write or talk about numbers using numerals such as “5” or “five”. We could also hold up 5 fingers, or tap the table 5 times. These are all different ways of referring to the same number.

There are also different types of numbers, such as whole numbers (1,2,3) decimals (1.48, 50.5), fractions (1/2, 3/8), and more.

**Number word**

The written word for a number (e.g. 6 is six).

**Number sentence**

A mathematical statement that shows how two quantities are related

e.g.3+8=11

**Zero**

The whole number between -1 and 1, with the symbol 0

Shows that there is no amount.

Example: 6 – 6 = 0 (the difference between six and six is zero)

Also useful as a “place-holder” so that you can write a numeral properly.

Example: 502 (five hundred and two) could be mistaken for 52 (fifty two) without the zero in the tens place.

**Whole Number**

The numbers {0, 1, 2, 3, …} etc.

There is no fractional or decimal part. And no negatives.

Example: 5, 49 and 980 are all whole numbers.
