Throughout history, people have been counting and making devices to help counting and to perform calculations. Initially these devices were based on physically changing things or moving things to represent the various phenomena and perform calculations.
Can you guess what was the first computer like?
Such a device is called an [[wikipedia:Analog_computer|analog computer.]]
Can you guess what these two images are? The one on the left is called the Abacus which was used to perform calculations with numbers by moving the beads. The one on the right is called the Antikythera machine which was used in Greece to calculate the positions of astronomical objects.
