Anyway, some of it clicked in when I went on the web. They were equations with variables and I was okay with that until they threw in a fraction. I'm not a dumb person, but I have to be shown how to do a math problem before I can do it. So I'm straining my brain and trying to make the rusted gears turn, which gave me a headache. Those gears haven't had to turn since sometime in college.
Then one of the gears clicked in and bonked me upside the head and said "What are you doing? Your sister is a math teacher and we live in an age of technology." I told my daughter to email my sister... the phone rang five minutes later. The funny thing is that while I was listening to just my daughter's side of the conversation, I also figured out how to do the equation.
Although my sister lives in the Portland area and we are in the Seattle area, we do live in the days of technology. It's not like in order to get information from my sister I have to send the Pony Express or even type out the dits and dahs of morse code.

That's "catch a clue" in morse code.
