I collect the formulas of Japanese high school mathematics for foreigners. There exist the formulas of high school mathematics. However, there does not exist formulas with derivations. So I write this book. The derivations of the formulas are most important points of mathematics. I show Japanese high school mathematics for foreigners. Japanese high school students study mathematics IA in 1 annual and IIB in 2 annual and IIIC in 3 annual.
