Answer 2

An abacus has beads that slide on rods. It can be used to count, add, subtract, multiply and more.

The most common abacus is split into two basic rows:

the top row for the "5"s, and
the bottom row for the "ones".
There are two beads in the top row, and five beads in the bottom one.

For example, 7 can be made by using one bead on the top row, and 2 beads from the bottom row, because 5 + 2 = 7
