By default, when you take input, the input is taken as string even if you input a number, so when you add those numbers, it will be concatenated instead of adding. Like, 2 + 3 = 23 instead of 5. So, to come out of this, you need to convert the input to integer number. To do this, use parseInt() function. Consider the following example: As integer: x = parseInt(prompt("enter no. 1")) y = parseInt(prompt("enter no. 2")) z = x + y alert(z) As String: p = prompt("enter no. 1") q = prompt("enter no. 2") r = p + q alert(r) See the the examples, hope it helps you
