$number += @_[$_]; ==>this is the mistake.

When you pass the array to the function, the default @_ will grab everything and store it.

And when you use the foreach, $_ will loop through the entire array and will have the current value when you process it.

Correct usage should be:

=======================
 $number += $_;

Your proglet works fine after this.

Hope you understood now :-)
