# Definition of Notation

Notation is a system of symbols that is used to communicate with other specialists in a field of study.

Notation is used in fields like music, mathematics and dance. The pictures show some examples of the use of notation in mathematics to make a statement precise, and notation in dance to describe the steps of a dance and how they fit with music.

For example, in mathematics we use the notation $\sqrt{4}$ to stand for the positive number that, when multiplied by itself, gives the answer $4$.
