Calculators are used to calculate, or solve math problems to come up with solutions.Hope that helped!
They used the abacus
Mercury is a heavy metal that is very toxic and is a liquid at room temperature. For this reason I do not believe that there would be any mercury in calculators. I do not know why mercury would be used in manufacturing. I don't believe is is commonly used in computer chips. Whether or not mercury is actually used in calculators or in manufacturing of calculators depends varies by manufacturer.

Calculators are used to solve maths problems quickly and reliably
Silicon based semiconductors are the most commonly used semiconductor material in calculators. Silicon semiconductors are also extensively used in computers.
Calculators do not typically contain gallium as a primary component. Gallium is a rare metal that is used in some electronic and semiconductor applications due to its unique properties, but it is not commonly found in calculators.
A semiconductor slice is used to make integrated circuits or ICs. It is also known as a semiconductor wafer or a semiconductor substrate.
Annuity calculators are used to calculate the returns on investments made in annuities.

GPA calculators are used for College students to keep track of their Grade Point Average.
Silicon.
it is metal.. so not used for doping.
Yes, magnets are commonly used in calculators to help hold batteries in place or to secure the calculator cover. Magnets can also be used in certain types of stylus pens for touchscreen calculators.
Calculators are amazing devices used for quick calculations. They use semiconductors in two places: -- in chips (widely known) -- in display An Integrated Chip, which performs calculations, employs transistors, FETs, diodes, etc. These are made up of semiconductors. The IC is the brain of the calculator. Next, the important part is display which used Liquid Crystal Display. In modern day calculators, Twisted Nematic crystal display is used where voltage changes must be made to increase or decrease the amount of light passing through them to create numbers. Instead of using different plates for the 7 segments and supplying separate voltage for each of them, a single plate is used and semiconductor in the form of FETs is embedded in glass so that voltage of every segment can be controlled by the semiconductor device and a common voltage source can be used. Nowadays, calculators form characters other than numbers which requires only a selected area to be supplied with voltage. This is accomplished using semiconductors.
