Number of Possible Combinations

  • There are two rods on an abacus: a tens rod and a ones rod.

  • Each rod can hold up to 5 beads.

  • With 4 beads, there are 5 choices for the first bead and 5 choices for the second bead, and so on.

  • Therefore, there are 5 x 5 x 5 x 5 = 625 possible combinations of beads.



Listing the Numbers in Ascending Order

  • The numbers can be listed in ascending order by starting with the smallest possible combination of beads and working up to the largest possible combination.

  • The smallest possible combination is 0 beads on the tens rod and 0 beads on the ones rod, which represents the number 0.

  • The next possible combination is 0 beads on the tens rod and 1 bead on the ones rod, which represents the number 1.

  • The list continues in this way, with each possible combination of beads representing a number in ascending order.

  • The largest possible combination is 4 beads on the tens rod and 4 beads on the ones rod, which represents the number 44.



Therefore, there are 625 possible numbers that can be made on the abacus using 4 beads, and they can be listed in ascending order starting with 0 and ending with 44.
