Using Mathematical Operators

For numeric data, there are four basic mathematical operations you can perform:

Using Operator Precedence

In mathematics, operators are given a precedence to determine how an expression is to be evaluated. Without rules of precedence, mathematical expressions could be ambiguous.

With an expression such as 3 + 4 * 5, the following calculations can be made:

•  If the addition is done first, you have 7 * 5, which is equal to 35.

•  If the multiplication is done first, you have 3 + 20, which is equal to 23.

The second option is the correct answer, because the rules of precedence in mathematics state that multiplication has a higher precedence than addition. Operators that have an equal precedence are evaluated from left to right.

PracticeScript follows the mathematical rules of precedence.
