If you come from a poor family and couldn’t go to a good school, could one book change your life? It did for Srinivasa, a bright young Indian boy. When he was 15 years old, he found a book about math. It was a book with 6,000 very difficult problems. While his friends played football on the road in front of his house, he worked out the answers to these problems. He answered them all by himself – without any help from anyone else. Then he thought of new problems and answered them too. Soon he was better at math than all of his teachers. A year later, Srinivasa was invited to study at university, even though he was really too young. However, he failed most of his exams. Why? Because he was only interested in math and didn’t care enough about his other subjects. He wrote about his ideas and sent his work to magazines. A British mathematician read his work and started writing letters to him. Later, he invited Srinivasa to go to England to study and work. In England, people didn’t care whether he was good at other subjects or not. By the time he was 30.
