Addition operator

In many programming languages, the addition operator ( += ) can be used as a way to add to a previous value. For example, in the Perl code below, the $example variable is first set to a value of “2”. The next line uses the addition operator to add “2” to the variable.

The computer processor ALU (arithmetic logic unit) performs the add operation.

$example = 2; $example += 2; print “Total = $example”;

When the script above is executed, the computer would print out “Total = 4” to the screen.
