Haven't heard from us for a long time? We aren't dead, just doing big background changes on our website... You will see everything as time goes by, but for now we will publish each time a group of lessons that will look like a roadmap that you can click on. For now, we have publish a group of lessons - Polynomials. This group contain lessons: http://www.mathemania.com/lesson/fundamental-theorem-algebra/
http://www.mathemania.com/lesson/factoring-polynomials/
http://www.mathemania.com/lesson/polynomial-equations/
http://www.mathemania.com/lesson/integer-solutions-polynomial-function/
http://www.mathemania.com/lesson/rational-root-theorem/
http://www.mathemania.com/lesson/irrational-root-theorem/
http://www.mathemania.com/lesson/descartes-rule-signs/
http://www.mathemania.com/lesson/graphing-polynomials/
http://www.mathemania.com/lesson/the-binomial-theorem/
This is only one thing that is animated, but expect more to come. We will do our best to make math more interesting and amusing at the same time for every mathemaniac. :) 

Converting decimals in fractions or percents, percents to decimals or fractions, fractions in decimals or fractions is rather simple method.

Achtung, achtung! :) There are few refreshments:
New updated slider with the latest lessons is placed at the top of a website. It will contain 7 latest lessons. It will replace the old fashioned way of presenting new lessons. Hope you like it.
A new lesson about Radical equations has been published - http://www.mathemania.com/lesson/radical-equations/.
Expect many more to come.

The inequalities that come in form: ax^2 + bx + c > 0 and ax^2 + bx + c < 0 are known as quadratic inequalities. To draw a graph of this type of inequalities is rather bit different than graph of equations.
