In fact, after becoming accustomed to abacus, students can do it with
only fingers, or even simply visualizing the beads in their mind.
That is why they use abacus as the first step to mental arithmetic.

Mental arithmetic gives some good confidence in handling numbers to the
student (so that they become less prone to errors). But other than that,
I am not sure of the use of it.
