The abacus remains in common use as a scoring system in non-electronic table games. Others may use an abacus due to visual impairment that prevents the use of a calculator. [1] The abacus is still used to teach the fundamentals of mathematics to children in most countries. [citation needed]
If this symbol refers to the total value of the slot (i.e. 1/72 of an as), then each of the two counters can only have a value of half this or 1/144 of an as or 1/12 of an uncia. This then suggests that these two counters did in fact count twelfths of an uncia and not thirds of an uncia.

Notice that each row of counters on the grid is just 22 multiplied by some power of two. In fact, the total value of the counters is the sum of two rows 22*8 + 22*1 = 22*(8+1) = 22*9. So the counters on the board actually represent the product of the two numbers, except it is not possible to "read off" the answer just yet.
