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.
Can you make 99 using your calculator if the 9 key the plus key and the minus key are broken?
One way is by using 3 x 33 = 99

Where was the slide rule made?
Slide rules have been made all over the world, in the United States, several European countries, China, Japan, and other places. Their technology is fairly easy, and could be set up anywhere, really.
Early on, from the seventeenth century, the best slide rules were made in the UK. About 1880, the best were made in France. After that, from about 1900, the best were made in the US and Germany.
What are Advantages of no calculators?
Being able to work without a calculator will give you a deeper understanding of maths and arithmetic, and the methods (either using your brain or on paper) used to reach a correct answer. A calculator won't show you how to work the calculation, but will give an answer at the touch of a button or two. It is best to learn without a calculator first, before relying on a calculator.

How can you find a factor of 4294967297 without a calculator or computer?
because it's not ending with a even number its not divisible by 2.
if the sum of the numbers is divisible by 3 the whole number is.
4 + 2 + 9 + 4 + 9 + 6 + 7 + 2 + 9 + 7 = 59
So it is not divisible by 3 as well. It's not divisible by five because it's not ending with a 5 or 0. I'm not going to do the whole list but you probably have to calculate this on a piece of paper. After a lot of calculating you will find it's divisible by 641.
The quotient is 6.700.417 which you will find is a prime as well So 4.294.967.296 = 641 * 6.700.417
Where is the Pascal Calculator?
Over the course of a decade, Pascal produced dozens of calculators, all of essentially the same design. They can be found in various museums; in particular, the Musée des Arts et Métiers in Paris has four of them on display.
What its uses of the napiersbones?
Napier's bones is a manually-operated calculating device created by John Napier of Merchiston for calculation of products and quotients of numbers.
How does one draw a cubular figure on a calculating device?
One would not go about doing this because there is no such thing as a cubular figure.
During 30 years as a professional statistician, I have never come across such a strange practice. The only thing that I can think of is that it is a flawed attempt to avoid division by zero. That, of course, is based on an assumption that the singularity is at zero.
