Math isn't hard. Love is.
I (the narrator) am a high school student who loves mathematics. I meet girls in high school. I and the girls enjoy solving math problems, as well as high school.
"Math Girls" books depict the beauty of math, the excitement of tackling difficult problems, and the fun of discussing them with friends. Beautifully typeset with LaTeX and the Euler Font. Suitable for middle school students to mathematicians.
Hiroshi Yuki is born in 1963. He is the author of many Japanese books about Java, Perl and mathematics. He is also known as the author of yet another Wiki clone (YukiWiki).
