India, I received an interesting email the other day that taught me a lot about your country. Do you know what is the population of India? A lot. 1.2 billion and counting. And all these billion people, millions are illiterate. In fact, India has the highest rate of illiteracy in the world. Rowan, you should be thankful that we allow fools like you to come to our country and get an education. Yes. If you don't mind me asking, Professor, what email account do you use? Hot mail. Sabir Bharti, one of those million illiterate Indians created.me. And we get back to the problem on the board. So can we solve that problem without using the number zero? No, we can't. And stop with the ridiculous questions. Arya Bhattasar, another illiterate Indian who invented the number zero.
