Arithmetic equations in alert?

Question

Hello I am making an alert that shows the addition of Number(num1) + Number(num2) in an alert box it comes up with what the user inputted and result but I was wondering how would I code it to show the whole equation, for example, "2 + 2 = 4" If the user put in 2 and 2.

I know how to get it to show the result but how can I make it show the numbers the user put in to get that result?

`alert(num1+ " + "+ num2+" = "+ (Number(num1)+Number(num2))` — Thilo, Jun 02 '15 at 23:45
@DanielAWhite: That "duplicate" is quite unrelated. Voting to re-open. — Thilo, Jun 02 '15 at 23:47
Using ES6 [template strings](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/template_strings): `alert(\`${x} + ${y} = ${x+y}\`)` — Oriol, Jun 02 '15 at 23:47

Assuming I understand what you want to do:

a = prompt('first number');
b = prompt('second number');
alert( a + '+' + b + '=' + (parseInt(a)+parseInt(b)));

Why do you convert the numbers to integers? – Oriol Jun 02 '15 at 23:50

How would I use that with a comparison operator ? – Nakayuma Jun 03 '15 at 00:36
Instead of saying 2 + 2 = 4, putting 2 ==3 = false I tried using the same formatting from the question above but it doesnt work. – Nakayuma Jun 03 '15 at 18:08
`a = prompt('first number'); b = prompt('second number'); alert( a + '=' + b + '==' + (parseInt(a)==parseInt(b)));` – dave Jun 03 '15 at 18:21
Oh okay I saw what I did wrong thank you! – Nakayuma Jun 03 '15 at 23:16
