Re: A question regarding dictionary entries

Well, my Gwr do have four fingers per hand. Maybe when they count in decimal
they use the palm or the fist for 5 and 10.........

At one point I was so fascinated with Base-8 that I developed a
multiplication table for my own use and instruction, also a table of (some)
squares, and (some of) the Na Kwæy Hu {Fibonacci) series-- all had
interesting properties. I managed to add, subtract, multiply reasonably
well-- division was more difficult!

This assumes that octal people have developed the concept of zero, and
place-notation, so that numbers are written out as
thousands--hundreds--tens--units. Obviously in practical terms that's going
to be 512 - 64 - 8 and 1 thru 7. Yes, it's Terra-centric, I know.

4*2 = 10, 4^2 = 20, 4^3 = 100 and of course 10^2 = 100.
3*4 = 14, 3^2 = 11  ha ha
7*2 = 16, 7^2 = 61

5+5 = 12, 6+7 = 15, 20+40 = 60 of course, but 20+70 = 110,  etc.

1,2,3,5,10,15, 25, 42, 67, 131 etc.
(I think I got those right.)
