Answer 1

Line 53: x = start();

Answer 2

Your `start` function could be clearer this way:

function start(){
var fst = Math.floor(Math.random()*10);
document.getElementById("fst").innerHTML = fst;

var snd = Math.floor(Math.random()*10);
document.getElementById("snd").innerHTML = snd;
return fst + snd;
}

Answer 3

Anna thankyou ma'am its working & please explain why we have to assign x to this calling function when all this start doing is just calling the function again
