jehan adam was a french mathematician who flourished in the 15th century .
he was secretary to nicholle tilhart , who was notary , secretary and auditor of accounts to king louis xi of france .
he published a manuscript in 1475 containing the first use of the terms `` bymillion '' and `` trimillion '' , which gave rise to the modern terms `` billion '' and `` trillion '' .
his usage referred to the long scale values of 1012 and 1018 respectively .
these terms have subsequently been revalued in english to the short scale values 109 and 1012 respectively , although the original values remain in long scale countries .
