Answer 4

@Iwan de Jong.
It will not work with + or - . I still suggest to use the Number function to convert the prompt string to a number before calcuating with it.

var x = Number(prompt("Enter a number:"));

Answer 5

var y = 5
do
var x = prompt("Enter a number:");
while (isNaN(x));
alert("The multiply is: " + x * y);
alert ("The sum is: " + Number(x) + y);
