Happy birthday to Maria Agnesi, the first woman to write a major calculus textbook and the first woman to be appointed as a university math professor.

For fun...solve one math problem every week. New problems are posted every Monday morning at 8am. Go to themathcontest.com to get registered.


Great advice!!!

A lot of mental arithmetic tricks amount to recognizing algebraic patterns in numerical problems. For example, seeing 89*91 as (90 - 1)(90 + 1) = 90^2 - 1^2 = 8100 - 1 = 8099.


Congratulations to Chris Yao and Matthew Ding at the State Math Competition!!! Chris Yao got 1st place in the Target round and 2nd place in the Sprint round for 11th grade! Matthew got 3rd place in the Target round for 10 grade! Way to go! #MATH.
