The window.prompt() can return either a string or a null. If user gives input the same input is returned in "string" format . If user don't enter anything then you get null.
Basically using + with strings will concat them.
You need to typecast the values read by prompt().

You can do as follows

let n =Number(prompt('enter no'));

in your case use:
document.write(Number(numberx) + Number(numbery));
