I’ll never forget when the cash register was broke at some store. She had to use a calculator to get the change right instead of counting up. I tried to explain it to her but you’d think I was explaining brain surgery.
It's so sad, seeing the destruction of our education system. Back in the 1950's, we were taught to use slide rules, but you had to know the basics of math to utilize them. Now kids are taught calculators, without understanding the principles they operate on. I'm proud of my kids, who embraced the idea of learning the basics behind the tools they use. They told me that all you needed to pass and graduate from schools today is to show up breathing. Schools don't teach real-world skills, unless you count how to use a prophylactic rubber.
