  • True, but you’ll save lots of time if you keep the ability to do simple math in your head.

    Classmates always wondered how I could finish the tests before the time limit while they weren’t even finished when the bell rang.

I don’t want to know how long these people take shopping groceries now that everyone has a calculator in their pocket.
