French Blaise Pascal invented the calculator in the year 1642. He did this so he can help his dad who is a tax collector. The calculator was made of gear wheels. One of the wheels had ten notches for each place-value that goes up to one-hundred thousand. The calculator worked when a wheel has moved ten notches after a revolution. The wheels on the calculator were moved by dialing numbers in different place-value columns Later on Gottfried Leibnitz improved it with his new machine that could add, subtract, and divide. The original compact calculator was the abacus. (If you want to learn more on the abacus go to TheSaptadipPage) The first commercial succesful calculator was made in 1886 by William Seward Buroughs (1855-1898). The first calculator that made direct multiplication was the "Millionaire" developed by Otto Seiger in 1894. The first hand-held calculator was made at Texas Instruments incorporated in 1966 by a development group.
Interesting Facts

I do not know how they invented the calculators with the technology back then so I'll keep researching for that, but what I do know is that the calculator was driven by gears.

Randy, the man in the tub was Archimedes. He was a Greek guy who discovered mass, or something like that. I don't see how he got into Dennis' page.
