“He went on to explain that if the question is something like 11.0241% of $289.31 your answer is going to look a lot like $30. If you get an answer far different from $30, start over.

My techniques exactly to try to get engineering students to have an idea of the “answer area” before resorting to their calculators. Of course, you know that the above will stump everyone in the White House.

I believe there was some media talking head (perhaps on The View?) who noted that Michael Bloomberg had spent something like $300 million on his presidential campaign. The media person complained that instead of spending that much on his campaign, he should have just given a million dollars to every living American.

That’s a fundamental misunderstanding of the “answer area”.

I ran into the same problem trying to teach someone the concept of a reasonable total.

If you have 15 bills and they all are under $2000 then the answer of almost half a million is not a reasonable answer. No matter how many times you insist that this is the answer the computer gave, something is wrong and you need to find it.

And when it comes to percentages they don't have a clue. You tell them something is 50% larger and they think it means the same as twice as large.

One article I read showed excerpts from books DeSantis had removed from FL schools. A math book had questions about Maya Angelou - where she was born, who she was, etc. I always figured math books should deal with math, more fool me, guess I’m not woke enough.

You’re right, yes it does.

I suspect billions of the ‘infrastructure’ boondoggle money was siphoned off by thugs and goons in ‘intelligence’, antifa, and third world grifters offering kickbacks to corrupt DC crooks.

“So the “teacher” doesn’t actually have to know any algebra at all.”

It’s the same for every textbook. That’s how one elementary school teacher can teach Social Studies, English, and Math without actually having 3 degrees in different subjects.

But the problem arises when they actually get a “bright” student who asks insightful questions. Then the teacher can’t answer.
