Sum of Numbers Array?!

Hello fellow Actionscripters,

I’m curious and I know there are many ways, but anyone have a good solution towards adding up the numbers in an array minus it’s current node?

If I am at myNumbers[3] for example, how do I add everything to the left of my current node such as myNumbers[2], myNumbers[1], myNumbers[0]?

var myNumbers:Number = [“123”, “45”, “111”, “54”];

Thanks in advance, geniuses…
