Abstract :
Multiplication is vital to the conduct of commerce but is time-consuming and error-prone. Among the many aids developed over two centuries to address these issues, the most widely used was the ready reckoner, a printed book containing tables of precalculated multiplication results that could be useful in business transactions.
