Umm why isn't this working

Question

I'm trying to make a multiplication calculator but its not working can you tell me why? var n = prompt("Enter a number", "");
var multiply;
var answer = Math.multiply(n);
alert("The answer " + n + " is " + answer);

Answer 1

Assuming it's JavaScript, n is a string. Multiply requires 2 or more arguments and can't process strings. Try this:

var n = parseInt(prompt("Enter a number", ""));
var answer = math.multiply(n, n);
alert("The answer " + n + " is " + answer);

Answer 2

math.js that defines multiply needs to be include as it isn't a standard part of JavaScript. Personally, I'd just do n*n or whatever you're looking for.
