About 110
Menelaus of Alexandria writes Sphaerica which deals with spherical triangles and their application to astronomy.

About 150
Ptolemy produces many important geometrical results with applications in astronomy. His version of astronomy will be the accepted one for well over one thousand years.

About 250
The Maya civilization of Central America uses an almost place-value number system to base 20. (See this History Topic.)

Diophantus of Alexandria writes Arithmetica, a study of number theory problems in which only rational numbers are allowed as solutions.
