The age thing has to do with Common Core. Those of us that didn't have Common Core math had to memorize. Don't forget we have 50 states, and they switched teaching styles at different times. So, my age where I lived didn't do memorization in math. But, I not only wasn't from there, back then I was constantly surprising people that I was legal to drink.

I'm chatty, so I talked to that person. They told me that they used to have more difficult problems, and no calculator. But, people weren't completing the form so they had to dumb it down.
