A subtotal is the total of one part of a longer list of numbers — a total that is not the final total. On a receipt in a shop, you see the prices of all the things you bought added up, and that number is the subtotal; then tax is added, and maybe a service charge or a discount, and only then do you get the real total at the bottom. So a subtotal is honest but unfinished: it is a true sum of what it covers, and it is waiting for more numbers to come.

A subtotal小計 is the total of one part是一長串數字裡其中一部分的總和 of a longer list of numbers — a total that is not the final total一個還不是最終總數的總和。On a receipt in a shop在店裡的收據上, you see你會看到 the prices of all the things you bought added up你買的所有東西的價格加起來, and that number而那個數字 is the subtotal就是小計; then tax is added之後加上稅, and maybe a service charge or a discount可能還有服務費或折扣, and only then do you get到最後你才會拿到 the real total at the bottom最下面真正的總計。So a subtotal所以小計 is honest but unfinished是誠實但還沒完成的: it is它是 a true sum of what it covers它涵蓋範圍裡真實的加總, and it is waiting for more numbers to come只是還在等更多數字加進來。

The word is mostly used for money and for spreadsheets. In a spreadsheet you might add up each month's sales, and each of those monthly numbers is a subtotal; the year's number is the total.

The word這個字 is mostly used最常用 for money and for spreadsheets在錢和試算表上。In a spreadsheet在試算表裡, you might add up你可能會加總 each month's sales每個月的銷售額, and each of those monthly numbers而每個月的那個數字 is a subtotal就是一個小計; the year's number全年的數字 is the total才是總計。

It is also a verb, used mainly by people doing accounts: "subtotal each column first, then add the columns." As a verb it is quite technical and you will hear it far less than the noun.

It is它 also a verb也可以當動詞, used mainly by people doing accounts主要是做帳的人在用: "subtotal each column first, then add the columns."「先把每一欄小計，再把各欄加起來。」As a verb當動詞用的時候, it is quite technical算是滿專業的用法 and you will hear it far less than the noun而且比名詞少聽到很多。

It does not carry any feeling — nobody uses it to mean "a small amount" or "not enough." A subtotal can be a huge number. The "sub-" is only about position in the adding-up, not about size.

It does not carry any feeling它不帶任何情緒色彩 — nobody uses it沒有人會用它 to mean "a small amount" or "not enough"來表示「一點點」或「不夠」。A subtotal小計 can be a huge number可以是一個很大的數字。The "sub-" sub-這個字首 is only about position in the adding-up只跟加總過程中的位置有關, not about size跟大小無關。
