Manual calculating devices are tools used for performing arithmetic calculations without the aid of electronic components. Examples include the abacus, slide rule, and mechanical calculators. These devices rely on physical manipulation or mechanical parts to facilitate mathematical operations. They have largely been replaced by electronic calculators and computers but are still valued for educational purposes and understanding mathematical concepts.
Calculating machines are devices designed to perform arithmetic calculations. Examples include the abacus, which uses beads to represent numbers, and mechanical calculators like the adding machine and the slide rule. More advanced examples are electronic calculators and computers, which can perform complex mathematical operations and process large amounts of data. These machines have evolved significantly, from simple manual devices to sophisticated digital technologies.
There are lots of applications of calculus; for example: calculating maxima and minima, analyzing the shape of curves, calculating acceleration when you know the velocity, calculating velocity when you know the acceleration; calculating the area of figures; calculating the volume of 3D shapes; etc.
Calculating clock is the first known calculating device made by Wilhelm Schickard. This machine can perform the basic mathematical operation, but canÕt show too large result which is limited to six digits.
Abacus was the first calculating device invented by the Chinese.
pictures of calculating devices with their inventors
The china had one with rows wooden round balls on wires, 3 rows of them, 3 balls & 3 balls =6 in the last row, that was add, to subtract it was to the left cool
Abacus, slide rule, computer, calculator.

The devices could do most of the calculation work by itself
The earliest recorded calculating device is the abacus. Used as a simple computing device for performing arithmetic, the abacus most likely appeared first in Babylonia (now Iraq) over 5000 years ago.
The device used for calculating and processing data in a computer system is known as the Central Processing Unit, or CPU for short.
Not as we now know them. There were, however, devices for calculating and then there was the human brain ...
because that's all they had but now we have didital ones that are better
