Too bad it takes half the elapsed time to get to the meat of the issue, viz., the tables themselves. The secondary refs to dimes and so on, might also be useful as a mnemonic device.

I would say it’s just the modern rendition of the way multn tables have generally always been taught: use a *chant*. Rap “music” is essentially a modernized chant IMHO. In that sense, the only really ‘new’ thing is the use of video.
