Operators:

There are in general two types of operators: unary operators that operate on a single value or operand; and binary operators, that operate on two values or operands. The symbol "-", for illustration, is both the unary operator for negation and the binary operator for subtraction.

Here are some of the general operators which can be used with numeric expressions:

+ addition

- negation, subtraction

* multiplication

/ division (divided by e.g. 10/5 is 2)

\ division (divided into e.g. 5\10 is 2)

^ exponentiation (e.g., 5^2 is 25)
