About Us

This is a list of teachers and professors that have contributed to this website.

My name is Svetlana Ryzhik. Math has been my favorite subject since middle school. Later, I came to love teaching math, and I believe that children can learn and improve their results through getting extra practice and extra help.

My name is Ninel Vapnyar. I immigrated to the United States from Russia in 1994.

In Russia, I at first worked as an elementary school teacher, and later, at about 30 years, worked as a professor at Moscow State Educational University; preparing teachers for elementary school education.
