They're also trying to teach that in math classes (it gets called "new" math) but the boomers are freaking out because "why can't they just do normal additions like we used to, this is so complicated".
So, as a childless Xennial, I have to ask... is today's "new math" the same "new math" that people complained about in the 60s?
If so, that's an awfully long time for something to be shunned as "new."
we never need to just do a long division.
Truth. I recently got a neuropsych evaluation and part of it was an unexpected (to me) IQ test. And staring me in the face, for the first time in ~30 years, was a few pages of arithmetic problems. Took me a minute to recall how to do decimal multiplication but it did come back to me. Long division? Nope. Had no freaking clue. Given that it was timed I just left blank anything I couldn't work out in my head. Maybe if I had time for trial and error I could have eventually figured it out. But one thing is for sure... the odds of me ever needing that skill again are fairly low.
