Javascript Math Operator not working!!

Question

Heres my code:
var minute = prompt("Minutes : ", "0");
var second = prompt("Seconds : ", "0");
var convert = minute * 60
var wait = convert + second
document.write(wait)

If you enter 5 min and 30 sec, it displays 30030 instead of 330. Please help!

Answer 1

Try this:
var minute = Number (prompt("Minutes : ", "0"));
var second = Number (prompt("Seconds : ", "0"));

Answer 2

Worked. Thanks!

Answer 3

js provide a lot of type convert. If you use something like that also will work:
convert/1+second/1
+convert++second
it happens because prompt returns string. and if you concatenate two strings "300" and "30" it will be string "30030"
