The evidence could be multiplied endlessly by anybody with access to a Google machine, let alone a good library.
Google multiplied that out for its user base to come up with its global timesaving estimate of 3.5 billion seconds each day.
The examples of mangled evidence could be multiplied, believe me.
mid-12c., multeplier, "to cause to become many," from Old French multiplier, mouteplier (12c.) "increase, get bigger; flourish; breed; extend, enrich," from Latin multiplicare "to increase," from multiplex (genitive multiplicis) "having many folds, many times as great in number," from comb. form of multus (see multi-) + -plex "-fold," from PIE *plek- "to plait" (see ply (v.1.)). Mathematical sense is attested from late 14c. Related: Multiplied; multiplying.
