Addition and subtraction on a generic abacus.

Summary

Description
English: In the image above, four counters of value one represent the number 4 (left-a), after attaching another three counters (left-b) that represent the number 3 we have a representation of the number 7 (left-c); that is, the sum 4 + 3. Similarly, starting from the representation of the number 7 (right-a) and eliminating a set of counters that represent the number 4 (right-b), what remains on the table represent three or the result of the subtraction: 7-4 (right-c).
