Re: Is this abacus back to front?

Actually, the number is 5653587 (you skipped a digit).
And if we're looking through the abacus from the back,
the number is ...7853565... .  If you can figure out the
significance of this number, you're smarter than I am.
But what is odd is that this abacus has Chinese-style
rounded beads, but has a Japanese-style arrangement
of beads (1 bead on the upper deck, 4 beads on the lower
deck).  All the Japanese sorobans I have seen (and finger-
manipulated) have angular beads, whose shape is like <>,
which presumably is easier to manipulate with your fingertips.
So it looks like this is a (politically correct?) hybrid
Chinese-style/Japanese-style abacus/soroban.
