Using calculator on Computers

Computers weren't invented for email or the internet.  They were never intended to be used to keep track of your bank accounts or 2nd marking period grades.  The very first electronic computer was created during World War II and it's intended function was to help American soldiers hit their target.

Often cited as being the very first electronic computer, the ENIAC was built at the University of Pennsylvania from 1944-46.  At that time the US Army was employing hundreds of young ladies with mathematical ability to serve as "computers" and physically do the math to create ballistics tables for military weapons.  The function of the ENIAC was to electronically do the math that previously had been done by human computers.
