{{PageDescription}}
|
|
* 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 ([[concatenation|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 [[semicolon]]s or [[comma]]s instead.
