He teaches topics from basic addition (2+2 = 4) till the college level mathematics (developmental mathematics). Khan teaches the students using the pen tablet as his blackboard and explains the concept in clearer manner with examples and diagrams. Now there are 2,400 education videos starting with basic mathematics till advance biology. Thereby Khan has decided to quit his job and take this work as full time. Soon, in late 2009, the videos started to attract more then 20,000 viewers. As his cousin's friends started to show more interest over the method of his teaching, he decided to post his lectures in YouTube (16 November 2006).
In 2004, Salman was teaching his cousin some mathematical problems over the internet using a Yahoo!'s Doodle notepad.
