What is the Difference Between Small Friend and Big Friend in Abacus?
Small friend and big friend are simple formulas. They help kids add and subtract fast on the abacus. Many parents ask this question when their child starts level 1 or level 2.
Small friend works with the 5 bead on the upper deck. Big friend works with 10 using the next rod. Both save time when there are not enough beads.
