+

The + plus mathematical operator performs addition on two numerical values or concatenate STRING values.

Syntax: return_value = number1 + number2

Description

A + sign also can indicate a positive numerical value, but it is not required.
Numbers used can be any literal or variable numerical value type.
Adding one negative value will actually perform subtraction on the other value.
Adding two negative values will make the return value more negative.
Addition and subtraction are the last operations performed in Qbasic's normal order of operations.
The plus(+) operator can also be used to add (concatenate) literal or variable STRING values.
PRINT can also use + operations on string values ONLY! Numerical values will need to be converted to strings first or be included using semicolons or commas instead.
