Y’all…

I had to go to FB to find out about fireworks tonight due to a passing rain storm. I haven’t been on FB in a long, long time.

There are people posting elementary school math problems and adults are arguing about the answers.

What is happening to this world? Did people forget how to do basic arithmetic?

@jerry I keep seeing stuff like this floating around, except it uses the non standard division sign (dot line dot) instead of / without brackets..etc. Very unclear. Then a bunch of people argue over it. Chaos ensues. Clarity of notation is important.
