The - mathematical operator performs subtraction on two numerical values or negates a single value.


Syntax: return_value = number1 - number2


Description

  • Numbers used can be any literal or variable numerical value type.
  • Subtracting a negative value will actually perform addition with the other value.
  • Subtracting a negative or negated value will make the return value more positive.
  • Addition and subtraction are the last operations performed in Qbasic's normal order of operations.
  • Subtraction cannot be performed on STRING values.
