kappaGreektenth Greek letter

Greek κάππα supplies the name of the tenth Greek letter; that letter also gave rise to the Roman letter K.

In context

Numberphile2:05

the letter iota comes to represent 10. Kappa is 20. And then we've got to now go to our 100's. So rho, which is the equivalent of our letter R, represents 100.
