Curatorial note

The line that the rest of the world calls Arabic. The decimal place-value system with a true zero was worked out in India and set down mathematically by Brahmagupta in 628 CE, where zero is treated as a number to be operated on rather than a gap to be marked. Everything in the positional column of this floor descends from it.
