| September 22, 2009 — Mathematicians from North America, Europe, Australia, and South America have resolved the first one trillion cases of an ancient mathematics problem. The advance was made possible by a clever technique for multiplying large numbers. The numbers involved are so enormous that if their digits were written out by hand they would stretch to the moon and back. The biggest challenge was that these numbers could not even fit into the main memory of the available computers, so the researchers had to make extensive use of the computers’ hard drives.According to Brian Conrey, Director of the American Institute of Mathematics, “Old problems like this may seem obscure, but they generate a lot of interesting and useful research as people develop new ways to attack them.” Lanjut Baca » |

Setiap negara bangsa, negara dan daerah pasti memiliki penyebutan sendiri untuk angka-angka dari satu, dua sampai dengan sepuluh. Misalnya angka tiga kita menyebutnya di Indonesia tapi di negara lain ada yang menyebutnya tri, three, san, tolu dan lain sebagainya.
Bahkan bila ada yang masih ingat angka-angka tersebut dalam bahasa daerah teman-teman masing-masing dari satu sampai sepuluh maka kadang ada angka yang penyebutannya sama dan ada pula yang berbeda dengan Bahasa Indonesia. Mungkin tergantung dari enaknya di lidah atau di telinga.
