Fantastic website for math teachers and students.

I have been waiting to come across such a website like coolmath.com.
It has everything for a math teacher. Of course, the actual target viewers are students but I think even parents who teach their children mathematics can use the site frequently.

As a mathematics teacher,I could always use mathematical games and puzzles. math problems that require to be solved mentally and quickly are great math teaching aids.


Coolmath has a ton of cool math games and puzzles, lots of really clear math lessons (Algebra and fractions), fractals, Calculus, Geometry, tessellations and more.

As Coolmath.com has aptly described, it is an amusement park for mathematics.The site is colorful with big fonts and it is fun browsing the coolmath.com

Free mathematic online application.

Generally I don't review any website that has no "about us" and " Contact us" page. This site offers no navigation at all.

Still, I am doing this short review on "Kanakku" a Tamil word that means 'mathematics' because it is my subject and I really was curious in finding what is in it and also the person's name who requested me to d a review seems to be a Tamilian name.

Kanakku he says "a free online calculator/spreadsheet that
does arithmetic, trigonometric, statistic, and conversion functions."

I appreciate Kumar Rajan's effort to create two video tutorials on how to use his invention. The two video clips are uploaded in Youtube.
