Parse the string values into integers and then sum it. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/parseInt This is because in javascript if you adding a number to a string it will be casted to a string. For example:

0 + '1' + '2' // 012

But with parse int:

0 + parseInt('1') + parseInt('2') // 3

Or you can cast to int with a simple plus also:

0 + (+'1') + (+'2') // 3
