No an abacus is definitely not a book.
It is a piece of maths equipment a child might use to help with their counting, adding, subtracting, division and multiplication.
Usually abacuses are made from wood or plastic.
You rarely see them around nowadays.
Because modern teaching methods involve powerpoints and calculators.
We have not much a need for an abacus.
Abacus:
A wooden (or plastic) frame, with about ten metal (or plastic or etc) tubes running along it, on these tubes are beads.
You can slide the beads across, on each tube is ten beads (usually), and sometimes each row different colours. Children learning maths will slide these beads across the tubes one at a time to count or do some sort of maths.
Basically it's an instrument used when you've ran out of fingers to count on.
Obviously not used so much nowadays. The abacus as first invented in: 2700-2300 BC. So it's an old mathematical instrument that kids used to use to count on.
