Answer 1

Just made a demo, there are anyway different ways to do the same thing and i tried to choose the more readable, try to experiment on your own the others... or why not? Make some controls.

What if i add a character "a" rather than a number?

Have fun! :)

Answer 2

You called in a bad way the function at the onclick (you forgot to insert the parenthesis) and you make a calculation between two DOM elements and not their value.

Basically this is a way to solve pretty easy:

function plus(){
var num1=document.getElementById("num1").value;
var num2=document.getElementById("num2").value;
return parseInt(num1) + parseInt(num2);
}
function answer(){
alert (plus());
}

In the first lines you obtain id's value and in the return value you make an addition between their value converting it in an integer number.

I edited, now it is more clear i hope! ^^

Answer 4

@Coder parseInt is a JavaScript method for type conversion, specifically for converting strings to Integers...
it is used like this :
var myNum = parseInt("100");
// this outputs 100.

Another method for similar type conversion is parseFloat(); for converting strings to Floats...
