Search engines, some types of face and voice recognition tech, topological analysis, seismic analysis to find oil underground, cryptography, and many more. Now, is this stuff most people need to know? Nope. But set theory can be a powerful tool in some areas of tech.

I feel sorry for these poor kids today, what with some jackass school administrator in Kansas trying to make the kids believe they are sexless purple penguins, to Michelle Obama’s North Korean starvation diet for lunch, and then some so-called “teacher” taking a simple, basic arithmetic problem and turning it into a convoluted mess. I don’t see this turning out well for the public schools, which might be a good thing.

Do you want to fly in an airplane designed by one of these “ math wizards”,.

I remember back in the ‘70s I took a class in the so-called New Math.

I had "new math" in the 70's as well. Finally, in my senior year of high school, I had a teacher that wouldn't put up with bull crap math. He was a pistol. He would rant and rave about how none of us (students) could do math. I swear he was pissed off 90% of the time. But he taught us math, algebra and trig in one school year. It really turned the light on for me and by the time I graduated college I had a minor in mathematics.

I have since help home school my children. Math is not difficult and it is not difficult to teach when approached pragmatically. Kids only need to learn and master 22-26 new things in a school year if you look at the breakdown of a real curriculum. My one daughter is a sophomore and is doing Calc I & II this year ... and she is no math wiz, but she gets it.

It’s so convoluted, I don’t understand the point of doing this exercise. Are they not teaching the addition/subtraction tables anymore?

So I can make 2 with 13945 and 78. And I can make a bunch of other numbers too. Cool. I’ll just answer 2 to any question now, because as long as there are at least 2, those 2 will be there. And I’ll name them Skippy and Fluffy. I love math now.

"Tell how to make 10 when adding 8 + 5."

Silly idea and a waste of time except possibly as an exercise in an abstract algebra course in developing the system of integers, starting with the natural numbers (positive integers + 0) using the Peano axioms, but it can be done. The teacher just screwed it up. Short version.

8+5 =
8+ (2+3) =
(8+2)+3 =
10+3 = 13

One of my friends posted something like this on Facebook the other day. It rattled my brain all day long. It just did not make sense.

Until I realized they are getting them to count on their fingers—in units of five and ten.

My daughter has a learning condition that doesn’t allow her to memorize multiplication tables and the like. Her early math days were a disaster, until the problem was diagnosed. A couple of years of special ed programs on the side allowed her to catch up and move along. They used techniques like this—amounting to counting on her fingers.

I understood it when its a special class for a specific reason. But this common core stuff just makes my head hurt. I cannot imagine it is any better for the kids.

I have 11fingers.— common core math. 1-2-3-4-5———6-7-8-9-10.

On one hand, start with #10 and count down. 10-9-8-7-6. Then add the 5 fingers of the other hand. 6 and 5 are eleven.

So or not so?

Michael Brown has 8 Swisher Sweet blunts.
Trayvon has 5 purple dranks.
Trayvon, Michael and Dorian Johnson smoked 3 marijuana packed blunts while working the math problem.
So, yeah, man, the answer is 10.

No doubt there is a penumbra in there someplace that will make it all clear.

I had crap like this forced on me in the early 60’s. This is the same failed modern math they tried way back then. I flunked because this method is not logical or reasonable. My parents taught me arithmetic their way and I have done very well with it, even to this day.

Common Core math: If 2 is a number and 1 is a number then: 2=1 and 1=2 .....

You seem to be mixing cardinals with ordinals, different critters which can't be added, subtracted, etc. Google is your friend might help if you want to know more about it.
