If you enter a simple mathematical expression, the software will calculate the result of the expression and enter that value in the field.

The available mathematical operators, in order of precedence, are as follows:

Operator	Description
/	Division
*	Multiplication
+	Addition
-	Subtraction

For example, if you enter 1/8, the value of 0.125 is calculated.

Operator precedence determines the order in which the mathematical operations will be calculated when more than one operation is specified. The operators are listed from top to bottom in order of operator precedence in the table. For instance, if you enter 6/2*3, the software will calculate 6/2 first and then multiply the result by 3, yielding a result of 9.
