JavaScript Addition

Question

I have this code

function MyFunction(){
var Num1 = prompt("Please enter the first number to add together");
var Num2 = prompt("Please enter the seond number to add together");
var Add = Num1 + Num2;

document.getElementById("output").innerHTML = Add;
}

and I want to add the two var's together but instead they add them like they are strings.
Is there any way to get by this using prompts or should I use a text box instead?

Thank you for any response given.

Answer 1

You can convert your numeric string into a number using the Number() function.

var Num1 = Number(prompt("Please enter the first number to add together"));
var Num2 = Number(prompt("Please enter the seond number to add together"));

For more info on the function, refer:
