# MIT’s One Laptop Per Child - the XO

By Murray Bourne, 01 Jan 2008

This is a great concept - the US\$100 laptop designed for kids in Third World countries.

It does not rely on the Internet for connectivity. Rather, it can detect other nearby laptops and students can communicate with them using WiFi.

There are several clever built-in learning applications (like a measuring application and various creativity apps including collaborative art and music activities). They can even do video-conferencing. It is all open source, hence the low cost.

HTML: You can use simple tags like <b>, <a href="...">, etc.

To enter math, you can can either:

1. Use simple calculator-like input in the following format (surround your math in backticks, or qq on tablet or phone):
a^2 = sqrt(b^2 + c^2)
(See more on ASCIIMath syntax); or
2. Use simple LaTeX in the following format. Surround your math with $$ and $$.
$$\int g dx = \sqrt{\frac{a}{b}}$$
(This is standard simple LaTeX.)

NOTE: You can't mix both types of math entry in your comment.
