With the UAbacus you can add and subtract numbers using the "logic method" for abacus computation. Those learning abacus computation can practice their computation skills getting help with a step if they become stuck and having the correct answer verified. Users who do not know how to compute using a Cranmer abacus using the logic method can support individuals who are abacus users by following the steps necessary to solve the problem as the individual works the problem on a Cranmer abacus.
