- And now remainder is what's left over when you try dividing a denominator into a numerator how much is left over that you can divide out.
所以剛才，我們運行了這個程式—— hello, world，然後編譯它，
- When you try dividing a denominator into a numerator,

- and write it in the numerator.
作為第一步，你需要像這樣寫出 1 到 10 所有數字的平方。
- Then subtract it with this squared number 81 to get 6 and write it in the numerator.
然後用這個平方數 81 去減它，得到 6，並將它寫在分子。
微積分被過譽了？它只是基礎數學！ (Calculus Is Overrated – It is Just Basic Math)
- Now expand the numerator to get this as x2 + 2x * h + h2 and minus this x2.
現在展開分子，得到 x² 加上 2xh 加上 h²，然後減掉這個 x²。
比例、費率與比率：你一定要懂的數學概念！ (Ratios Rates and Proportions)
- If we see a fraction 2 over 1, or if we see a fraction 4 over 1, or 5 over 1, or a million over 1, we're tempted to kind of get rid of the denominator and just write the numerator part.
如果我們看到 2/1 的分數，或是 4/1，或是 5/1，或是百萬分之一，我們就想把分母去掉，只寫分子。
- You might be able to do the math in your head and say, "Well, I know this car has a better miles per gallon." But it's a little bit easier if we just divide the numerator by denominator.
你可能可以在腦袋裡算一下，然後說「我知道這臺車的每加侖英里數比較好」。但如果我們直接把分子除以分母，會比較簡單一點。

- We call the top number of a fraction the numerator.
分數上面的數字我們叫做分子。
- Then we need the fraction bar, and now we need the numerator, the top number.
然後我們需要分數線，現在我們需要分子，上面的數字。
零食公司恐因「MAHA」法規損失百萬美元！ (How Snack Companies Could Lose Millions Of Dollars Over ‘MAHA’ Laws)
- Numerator estimates those restrictions could reduce food and beverage sales by as much as $830 million this year alone.
Numerator 估計，光是今年，這些限制就可能讓 food and beverage sales 減少高達8.3億美元。
