Stupidly Simple Flash Question

That I cannot find an answer to…

how do I take a variable with the value of 2

and a variable with the value of 5

and add the two variables so that they equal 25… (and not 7)

This is what I am trying to work with:

var month:String = today.getMonth();
var date:String = today.getDate();

I don’t want to add the numbers…rather create a string that combines them…

Thanks!!!
