Homework - Concatenation vs addition, help appreciated
Hey
I'm taking a beginner class and an assignment I was given was to create an equation with JavaScript that web viewers could use with whatever inputs they chose. Here's the source code:
javascript Code:

var a; var b; var c; a = prompt("a ="); b = prompt("b ="); c = prompt("c ="); var result; result = a + b + c; alert(result);
My problem is that

concatenates the values instead of adding them; I searched and found that applying parseInt(variable) fixes this and tried it with success, but I was wondering if there is a simpler way, a function that performs "result = a + b + c" with addition rather than concatenation. I've tried various incarnations of "result a + b + c" and haven't been able to overcome this.
I appreciate any advice and thank you for reading this post. I also apologize if this question has been broached before.
Thank you
