Answer 2

Answer:

For upper beads (5's), use your pointer finger. *For lower beads (1-4), use your thumb to add and pointer to take away.

Always place the abacus scale on a flat surface. (4) The value of cleared abacus scale is 0.

fifty

Reading from left to right now, each of the four fingers on your left hand equals ten; the left thumb equals fifty; the right thumb equals five; and each of the four fingers on your right hand equals one. Now construct different numbers on your own.

The beads above the crossbar are known as heaven beads, and those below the crossbar are called earth beads. The numerical value of each bead depends on its location in the abacus. Each heaven bead has a value of five times that of an earth bead below it. Each rod represents columns of written numbers.
