JavaScript Operators

x = 5, y = 2, calculate z = x + y, and display z:

var x = 5;
var y = 2;
var z = x + y;
document.getElementById("demo").innerHTML = z;

Why are you posting here? This question is nearly 5 years old.
function hi(){
var x=document.getElementById("f").value;
var y=document.getElementById("ff").value;
alert("x ="+x+"y ="+y);
var z=x+y;
alert("z = "+z);// here i getting the answer 56 if the value of x=5 and y=6

Your inability to correctly copy the code from the accepted solution, which was posted SIX YEARS AGO, does not qualify as a new "solution".
