Heard on the radio: “and times that by [some number]”, where that refers to a number. This is the plural N times (in expressions like 6 times 10) converted to a verb meaning ‘multiply’. About 50 years old, this conversion supplies a short, English-based substitute for the longer, Latin-derived verb. In so doing, it swallows up the historical plural suffix within times, making it now just the final consonant in the verb times.
It’s in OED3 (March 2012):
trans. Math. colloq. To multiply (a number). Also occas. intr.

The 1886 cite looks like the conversion of quoted material, but the rest have times ‘multiply’ — including the verb in the PST in the 1997 cite: timesed.
