+ Operation
  Operation of addition.
Syntax  x+y
Notes Both operands are either numbers or matrices. In the latter case, the dimensions of the operands must be equal, lest '+' return an error. Additionally, '+' performs string concatenation.
Examples
-- String Concatenation:
   str = "Hello "+"World";
--'str' now holds "Hello World".
