Transcript of Calculator
When was the product invented?
The first mechanical calculator was invented 1642 by Blaise Pascal. The first electronic calculator was invented in 1960 and was based on cold-cathode vacuum tubes where orange discharge tube displays were used.
What need did the product address?
The calculator addressed the need of being able to do complex math on the go with speed.
Any existing patents...
There is many existing patents of a calculator, here is some patents still in production:
Who invented the product?
Blaise Pascal along with Wilhelm Schickard was one of two inventors of the mechanical calculator in the early 17th century. Pascal made his invention in 1642. The electronic calculator of 1960 was invented by Bell Punch Co. in Britain.
How was the product originally made?
It was built from the thought of the extensive history of tools such as the abacus, developed around 2000 BC.
What materials were originally used to make the product?
The materials used for the mechanical calculators were wood for the case and metals for the gears and dials. For the first all electric calculators, vacuum cathode tubes were used.

Why were these improvements made?
Improvements were made for users to solve more sophisticated problems, for better performence, faster calculation, and to be more user friendly.
What is the global impact on society of the invention and subsequent innovations?
The calculator has a immense impact on the world and society because it has helped make work and projects be completed at a accelerated-rate.
What improvements have been made to the product?
Liquid-Crystal Displays (LCDs)
Lower power consumption
CMOS(complementary metal-oxide-semiconductor) technology for battery-operated models
Solar cells(in some models)
Financial Calculations(unit, currency, number-system conversions, or engineering calculations)
Programming capabilities(updates for example Texas Instruments)
Who uses the product?
People who use calculators are students of any age, school teachers, professors, and workers(banks, corporate buildings, offices, etc).
If you had the ability to change this product in any way, what would you change?
We would add a camera that would read the problem/equation and instantly solve it. It would also have a built -in clock.
