Do you know why the Chinese abacus is the type of abacus most often pointed out as the ancestor of digital computer? The answer to the question may lie in the fact that the Chinese abacus has two heaven beads and five earth beads along each rod, and thus that makes the difference from other types of abaci. The Chinese abacus is commonly used for working in decimal, but it may be used as well for hexadecimal numbers. Note that when all beads along a rod are set then the sum of bead values would exactly be equal to 15 or F. Hexadecimal numerals are widely used by computer system designers and programmers because they provide a human-friendly representation of binary-coded values.
IF there are complains about a certain type of processor being slow in a certain type of arithmetic, maybe rewire the microcode to a different process. Stacks.?
From the class types of shown abacuses, Please click on drive.google.com/file/d/1mfNSa0IFHNjrgqs4yh9Ej0h4PqHXN_O9/view?usp=drivesdk Which abacuses would be convenient to compute numbers that have either decimal points or fractions? Definitely the Basic and Classic type abacus.
The Chinese 2/5 abacus is for a bsse 10 system. Dunno, maybe it can be used for a base 16; but it definately works for base ten.

No sir.. we didnt know that.
Thanks for edifying us.. 😊
I usually make my abaci.
I just missed the Mayan abacus which is base 20. There are 3 upper beads and 4 lower beads.
🙂
Thanks so much!!
No problem! I’d give you a high-five if I could reach through the screen! 🤚😄

🤔
I have. One
great.. are you using it?
*Gosto do 9 contas… melhor que fazer duas contas…*
Sorry.. don't understand that language..
A 5/1 abacus would be in base 12
✍️
I have a one too
Hope you are using it..
Cool.
Thanks Austin
