A calculator is a device that is used for performing numerical calculations. The first calculator was the abacus, which changed into constructed as a wooden body with beads sliding on wires. Calculations had been made via moving those beads up and down the wires. The abacus was very a great deal in use lengthy earlier than the adoption of the written Arabic numerals, and it’s far still used by a few traders in China and some other place in Asia.

There are greater complex clinical calculators which can be useful for engineering and accounting. They help in trigonometric, statistical, and mathematical functions that make the paintings less difficult for the scientist and engineer. The maximum advanced calculators may even display images, are programmable and encompass laptop algebra structures capabilities.
