Finally, I reached the last section of my maths textbook. It surprised me that I reached it. When I began it this January, I was afraid that it might be too difficult for me to finish it to the end. I was also surprised that I could reach the last section by this time this year. I had gathered that it would have taken me longer to finish it. In the last section, I am learning statistics and probability. I have just finished the first part of this section and learned about mean, median and frequency in the part. I only have three parts to finish the book.

ついに最終章まできました。ここまでこれて驚きです。1月に始めた時は、難しくて、最後までやれないのではと思っていました。また、この時期にここまでこれたのも驚きでした、終えるにはもっと時間がかかると思っていたからです。この章では、統計と確立を学んでいます。最初の項で平均、中央値と度数を学んだばかりです。残り３項をやれば終わりです。
