The calculator has a long and rich history. Trying to figure out who invented the first calculator is a difficult question.Calculating devices, such as the abacus, were used in ancient times. The abacus was invented in 3000bc by the Chinese.Eventually, other calculating devices were invented: such as the sector and the slide ruleMechanical calculating devices began to be developed in the 15th century. Wilhelm Stickard invented a mechanical adding machine in 1623.Blaise Pascal worked on the calculator for three years between 1642 and 1645. This calculator, called the Pascaline, was like a mechanical calculator of the 1940s. He created it to help his father with tax collecting.In 1673, Leibniz invented the first calculator capable of performing the 4 fundamental arithmetic operations: addition, subtraction, multiplication and division.The "push button" calculating machine was not invented until 1902, by John Dalton. These were called "Dalton adding machines".Bell labs became the next major player in the history of calculators, as the history of calculators begins to merge with computers.Researchers at Bell Labs begin to investigate the potential of using binary to perform arithmetic. A rudimentary mechanical device was created for adding 1-bit numbers together as the first proof of concept. Soon, George Stibitz creates the first proof-of-concept 1-bit adder using telephone relay technology.2 years later, the first 16-bit adder is invented, using vacuum tube technology.2 moths later in January 1940, Stibitz completes his Complex Number Calculator (later called the Model I Relay Calculator). This was the first calculator to be controlled remotely through telephonelines.Almost 2 years later, the Z3 was invented by Zuse in Germany. This is the first calculator capable of floating point operations. He sets the standard for how floating point numbers are represented, which is still used today.From here on out, Calculator history becomes computer history. Further development of computers/calculators is driven by the military during World War 2, mostly for cracking encryption.

Don't shy away from fractions. If someone asks for 1/10 of a number, you are being asked to divide that number by 10. So, 1/10 of 300 = 300/10. 300/10 = 30. In other words, if you write 30 on a piece of paper 10 times and add it together, you'll get 300! Let's try another one. 1/10 of 16450 = 16450/10. 1/10 of 16450 = 1645.

Pascal had the idea to invent the calculator while observing and aiding his father's official work as supervisor of taxes at Rouen. He saw what a strenuous and complicated it was to do the math, so he decided to make a device that would simplify the process.
1642 - 1645
No, the very first mechanical calculators could only add and subtract. The first mechanical calculators were invented in 1623 by Wilhelm Schickard, followed by the Pascaline, invented in 1645 by Blaise Pascal. However, calculators that could multiply and divide were in use by the 19th century.
Blaise Pascal worked on the calculator for three years between 1642 and 1645. This calculator, called the Pascaline, was like a mechanical calculator of the 1940s. He created it to help his father with tax collecting.However, the first calculators were abaci, and were often constructed as a wooden frame with beads sliding on wires. Abacuses were used centuries before the adoption of the written Arabic numerals system and are still used by some merchants, fishermen and clerks in China and elsewhere.The first mechanical calculator was made by Blaise Pascal of France, called the Pascaline, in 1642.The first calculators were abacus frames. These go back to earlier than 2000 bc. Names and details are unavailable; they have been long lost. The slide rule was invented by W. Oughtred in 1632. The first mechanical adder dates to about 1650 by Blaise Pascal in France. The first practical adder/lister was patented in 1885 by William Burroughs of Rochester, New York. The first hand held calculator was invented by Jack Kilby, Jerry Merryman, and James Van Tassel in 1966 at Texas Instruments.
