The * / + - operators multiply, divide, add, and subtract. Multiplication and division have precedence over addition and subtraction; otherwise, evaluation is left to right. Parentheses can be used to change the order of evaluation. The following are the arithmetic @functions.

Function	Description
@Abs(number)	Calculates the absolute (unsigned) value of a number.
@ACos(cosine)	Calculates the arc (inverse) cosine of a cosine.
@ASin(sine)	Calculates the arc (inverse) sine of a sine.
@ATan(tangent)	Calculates the arc (inverse) tangent of a tangent.
@ATan2(x; y)	Calculates the arc (inverse) tangent using the tangent y/x of an angle.
@Cos(angle)	Calculates the cosine of an angle (in radians).
