May be this is my new posting, although I used to write in this blog but I have deleted all because they is many kinds so this blog becomes inconsistent.

Nah, because I have many time recently so I want to write again about materials of mathematic and science with English. They are mathematics for junior and senior high school, physics for junior and senior high school, chemistry for senior high school, mathematics for lectures such as calculus, linear algebra, linear programming, multivariate analysis, operational research, etc.

I will post one posting in every saturday



I hope that this blog is very useful for all persons that interest with mathematics and science lessons.

Wassalamu'alaykum Warahmatullahi Wabarakatuh
