I don’t think the lattice mult method is easier.
I don’t agree with the suspicions mentioned in #79 — not say to, however, the poster isn’t correct.
I didn’t necessarily follow the conventions when I was a kid, and yet ranked very, very high locally and nationally. So I don’t automatically object to departures from convention — either the techniques work or they don’t.
I’m noticing a lot of goofy techniques being taught today. But they work. And some of the techniques offer clever ways of analyzing and solving problems.
If I were the math czar, I’d start the noobs on circles and triangles with supplemental add/mult.
In Baraq's math, the answer to every problem is "one trillion".
AH! Thanks for reminding me!
I just got a bottle of Glenlivet yesterday afternoon.
Time to crack that suckah and put it with some ice!!!
This will be an example of what we can expect from CommieCore story problems:
The ‘Evil Lumber Company’ cut down 12 trees while only re-planting 3 trees. The greed of capitalism damaged Mother Gaia by how many trees?
if you say so...
Lattice multiplication is Chinese?
I didn’t know that.
but how well does it work when you have to add ten or twenty or more numbers???
enjoy...
>> but how well does it work
Sorry, what is “it” that you’re referring to?
I was just telling my Wife, “The top two countries in math are Japan and India (I think). Why don’t we send some of their best here to train our teachers to teach math better to our kids?”
But, the answer to why is obvious: They don’t WANT our kids to be good at math.
They want drones.
Napier’s bones gives the answer within the square, this gives it on the outside.
Visually they do to strikingly similar.
p.s. i forgot the article is about subtraction, do they still teach children to add the old way also?
What a bizarre way to subtract. It took me about 20 minutes to figure out how and why this process works, but I can think of no reason to actually teach this to children.
I teach 7th grade math in a public school, and I do NOT have 20 minutes to figure this out...
I’d have to look at the text books to give you an accurate answer. They were a few years ago.
It would be wise for those two nations to ensure the US stays strong.
Agreed.
Like I said, though. I was just guessing.
The purpose is to confuse and disable......with the ultimate aim of creating obedient wards of the state.
they are re-wiring the brains to think “collectively”
I think you have solved the math problem!
Is that a joke?
