WHAT IS ZERO?

Science Illustrated - - ASK US -

The num­ber zero marks the di­vid­ing line be­tween neg­a­tive and pos­i­tive num­bers. The digit also fills empty spa­ces in num­ber sys­tems, in which the po­si­tions of in­di­vid­ual dig­its de­ter­mine the mean­ing of a num­ber. In the dec­i­mal sys­tem, the zero of 108 in­di­cates that the space holds no value – it does not in­clude any tens. The mod­ern zero was in­tro­duced in 628 AD by In­dian math­e­ma­ti­cian Brah­magupta.
