Take an online journey through the history of math

Around 1900 B.C., a student in the Sumerian city of Nippur, in what’s now Iraq, copied a multiplication table onto a clay tablet. Some 4,000 years later, that schoolwork survives, as do the student’s errors (10 times 45, for example, is definitely not 270). The work is a reminder that no matter how elegant or infallible mathematics may seem, it’s still a human endeavor.

That’s one lesson I took from “History of Mathematics,” an online exhibit developed by the National Museum of Mathematics in New York City and Wolfram Research, a computational technology company….
