Question

What did early man use to calculate?​

Answer 1

Early humans counted and performed simple calculations using tools such as their fingers, notches in sticks, knotted strings, and pebbles. Most early cultures evolved some form of a counting board or abacus to perform calculations. Pencil and paper eventually replaced these early counting boards, but a modern form of the abacus may still be seen in use in parts of Russia and Asia in the twenty-first century.
