## What are the two early counting devices?

Examples of early counting devices are fingers, toes, stones, sticks, pebbles, cowries among others. The history and development of computer can be traced back to the studies of Mathematics which started with counting.

What was before calculator?

An abacus is a device composed of beads that slide along rods, which fit into a frame. In ancient times, the abacus was used as a calculator; it aided in performing mathematical processes like counting, addition, subtraction, and multiplication.

What was the earliest form of counting and what counting tools were used?

The first method of counting has been argued to be counting on fingers. This evolved into sign language for the hand-to-eye-to-elbow communication of numbers which, while not writing, gave way to written numbers. Tallies made by carving notches in wood, bone, and stone were used for at least forty thousand years.

What is early mechanical device?

Mechanical Counting Devices – Abacus, Napier’s Bones, Slide Rule. The abacus was one of the first adding machines. The abacus is made out of beads strung by several wires. The position of a bead determines its value. Thus a few beads are required to represent large numbers.
