我正在嘗試從這段代碼中將我的總數加在一起，但不知道該怎么做。這是我一直在研究的腳本，他們每天賺的錢都會翻倍。<script>    // asks for the days you worked    var daysworked = parseFloat(prompt("daysworked", "100"));//equation and table for the days worked    for (var days = 1; days <= daysworked; days++) {        document.write("<tr><td>"+ days +"</td>");        // here is specifically the equation and how i output it         document.write("<td>" + "$" + ( Math.pow(2 , days - 1)*0.01) +"</td></tr>");我應該如何計算賺取的總金額？
