It is impossible today to imagine a world without what are known as Hindu-Arabic numerals. These nine symbols or digits (1 to 9) and zero (0) – crucially, together with the system of arranging them in place value – are at the very heart of so much of modern life. Without them there would be no computers and no space travel. Indeed, there would be precious little science, technology or medicine of any kind, to say nothing of mathematics itself.
