# Numeric Calculations

Usually, numeric calculations are performed using
arithmetic expressions
that can be used in operand positions and, in particular, on the right side of the assignment operator`=`

.
Numeric functions with a numeric return value can be used as operands of an arithmetic expression. As well as the numeric functions, some
system classes are also available. Finally, four standalone statements can be used for the basic arithmetic operations.
