■書評/Book Review
『やさしい高校数学(数1・A)』が分厚くて時間かかったこともあり、今度は薄めで入門解説が手厚い種類の参考書を選んだ。
前評判通り、各単元の最初にある解説が概念を説明していて非常に素晴らしい。
但し、こちらもやはり、ある程度計算練習を積んだ人でないと、説明読んでもわからない上、練習問題が解けない。
高校の入門用参考書を通して、数学はまず、「理屈・理解抜きにまず簡単な計算からとりかかる」ことが大事だと思い知らされた。私のような数学苦手な人だけかもしれないが。

The book "やさしい高校数学(数1・A)" is thick and took time to finish and I chose one that is thin and a guide of that for beginners is defenitely detailed.
As ballyhooed, the first guide in each section of this book is excellent for explaining concept.
Though, this book also requires readers to finish calculation practice because the explanation is hard to understand and included questions can't be solved without practice beforehand.
I was strongly made to realize "Beginning with easy calculation without any logic and reason" is crucial. It might be adapted for those with poor ability in mathmatics like me.
