February 7, 2024: Studying Maths (37), Proportions （数学の勉強（37）、比率））

I have just finished doing the proportion part of the maths. It was easy to understand and the questions were not too difficult. Next is the last part of algebra and functions, which is the binomial expansion. But I have only finished a quarter of the book.

　「比率」を終えたところです。分かりやすく、問題もそれほど難しくありませんでした。次は代数と関数の最終パート「二項定理」です。でもまだ本の4分の1しか終わっていません。
