i still don't see how it's easier... also pls see post #79 i still don't see how it's easier... also pls see post #79My Son explained it to me:
“Take the top number of the problem, and put the bottom number vertically to the right. Keep the numbers equally separated as you would the old way, and put boxes to the lower left side. Then multiply the numbers at the top with the numbers at the side and put the answer in the boxes that they cross, then add diagonally lower left. The answer will ride along the outside of the boxed on the lower left from top to lower right.”
Mind you, I’ve been drinking.
If my above interpretation of what my 13-year-old Son said to me makes no sense to you whatsoever, pour yourself a glass of Scotch.

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.
