### Who invented Calculators?

Blaise Pascal invented the first digital calculator in 1642  at the age of 16 in France to help his father with tax collection.  His device was also called the Pascal's calculator or the Pascaline or the Arithmetique.  In 1649 Louis XIV of France  gave him the exclusive privilege for his design and manufacturing rights for his calculating machines in France.

1642.

### When the patent was granted on the Calculator?

William Seward Burroughs was a bank clerk who thought of having a machine calculate all  the boring calculations of adding and subtracting.  His first adding machine weighed 63 lbs! Burroughs's adding machine did not have a zero. If no number was pushed in any of the rows then it was recorded as a zero for that row. The final number was printed on a tape like today's cash register tape. He filed a patent for his machine. In 1893 Burroughs received a patent for his improved calculating machine, which had an "oil-filled dashpot" which was hydraulic.  The hydraulic dashpot device helped  the machine to  operate properly and no matter how it was pulled got the right answer unlike his first machine which gave different answers depending on how people pulled the lever.

### What is a Calculator?

• Calculator is nothing but a tiny electronic device used for calculating arithmetic operations like addition, subtraction, multiplication and division.
• The first digital calculators were invented by Blaise Pascal and he worked for three years on the calculator’s that is from 1643 to 1645. Blaise Pascal is the father and creator of calculator and later based on his invention many other new designs and developments were made for these calculators.
• First simple calculators are used which are used only for basic operations later complicated calculators were developed which can handle operations like exponential, roots, logarithms, trigonometric and hyperbolic functions.
• Calculators became more advanced in the  1970s. They were portable and they are operated through battery power. The first portable calculators were invented in 1966 by Jerry D. Merryman, James H. Van Tassel and Jack St. Clair Kilby.
• The complicated calculators performing various operations are most probably used by engineering students today. Using calculators helps you to save time and reduce paper work.
