My program is supposed to be a basic calculater, but the addition part isn't working. All advice is very helpful.
var number1 = prompt("Type a number")
var number2 = prompt("Type a number(it can be the same or diffrent.)")
var ask = prompt("Do You want to ADD these numbers, SUBTRACT theese numbers,MULTIPLY theese numbers, or DIVIDE the numbers?(Type the first word)").toUpperCase()
var sum = number1 + number2
case'SUBTRACT': var diffrence = number1 - number2 console.log(diffrence) break; case'MULTIPLY' : var product = number1 * number2 console.log(product) break; case'DIVIDE': var quotient = number1 / number2 console.log(quotient) break; default: console.log("PLEASE CHoose an option that was given.")
