This site primarily focuses on Indian students from classes 6th to 12th Std.
Maths Club has lots of jokes, puzzles, a Maths quotient test (do try it!), a section on ancient Indian Mathematicians, some real gems from Leelavati, and so on. "We Recommend" section has many useful links to sites related to Maths. There is a collection of interesting articles like different kinds of numbers, story of zero, story of pi(). You can also contribute! If found suitable, your contribution will be included in "Reader's Contribution" section, along with your name/email address.
Vedic Maths : You will be proud to be an Indian!
Class Rooms contain lots of theory, examples and exercises (with answers). All this material is taken from books by M.L.Aggarwal. There will be model test papers and material for competitive exams.
Professor Theta is a multi featured question answering service. Anybody can post a question (mainly from 6th to 12th standard level) and anybody can reply. If nobody replies, professor Theta will attempt it.

However in professor Theta's message board, you can type in only plain text. Here are a few tips on typing maths on your keyboard:

Don't use tabs!
Good math notation is mostly a matter of spacing, especially when an expression takes up more than one line of text. It's important to use the space bar to line up text, NOT the tab key. Since the number of spaces equal to one tab varies from computer to computer, what might look right to you could be unreadable for someone else.
Fractions
There are two acceptable options for typing fractions. For example, "1 over 3x" may be written as
```
       a) 1          b) 1/(3x) 
          --
          3x 
```
Both notations are correct, but (b) is easier to work with. However, you must be careful to put parentheses in the right place.
Exponents
Usually the symbol ^ is used to represent exponent. For example,"x squared plus x to the power 3y" is written as
x^2 +x^(3y)
Subscripts
The most standard way to write p sub 1 (p₁) is p_1. Usually writing p1 is sufficient.
Square and Cube Roots
a. "The square root of x" can be written sqrt(x).
b. Since there's no easy way to write cube root symbols (and higher), it's best to express your root as a power. "The cube root of eight" can be written as 8^(1/3).
