Javascript numbers concatenate instead of adding but typeof is number not string

Question

I am new to javaScript. I am building a calculator here

I have stored the input values in variables so that I can eventually manipulate the results to perform calcul

Instead of using parseInt, you can multiply number by 1. Its much faster and easier method to covert datatype.

$(document).ready(function () {
    var theTerm = $("#theTerm").val() * 1;
    var theRate = $("#theRate").val() * 1;
    var thePrice = $("#thePrice").val() * 1;
    var theTax = $("#theTax").val() * 1;
    var theDown = $("#theDown").val() * 1;
    var theTrade = $("#theTrade").val() * 1;
    var theResult = theTerm + theRate + thePrice + theTax + theDown + theTrade;

    $("#calculate").click(function () {
        alert(theResult);
        alert(typeof (theResult));
    });
});
