Answer 1

// It works, you needed to make some tweaks in it...

var x = Number(prompt("Please enter first number"));
alert(x);
var c=prompt("Please enter operation");
alert(c);
var y=Number(prompt("Enter second number"));
alert(y);
var res;
switch(c){
case "+":
res=x+y;
break;
case "-":
res=x-y
break;
case "*":
res=x*y
break;
case "/":
res=x/y
break;
};
document.write("Result is:"+res);
