I'm trying to keep all these alive! I have old fashioned clocks, and maps in my car. I rarely use a GPS, love to drive around a little lost in the hills around here. I'll always have the sun! I do as much math in my head as I can.
I was a math tutor ten or fifteen years ago. I had one student who was studying for a college entrance exam, the SAT. A star pupil mind you. He was every teacher's success story. He could not multiply a number by ten without his calculator.
