Re: [FRIAM] This is how the Japanese multiply. (Math, not biology)

2018-11-03 Thread Frank Wimberly 
Some applied math is real math by my definition as is some CS.  Jon, Hywel
and I were reading Schutz on general relativity.  It was close to being
"real math"  but I was quite frustrated.  He talks a good deal about the
metric tensor but never really defines it.  As far as I can see it's
neither a metric nor a tensor according to the definitions I learned in
math classes.

"Real" and "real math" are two different things.  My definition of real math is 
exposition of the form "definition, theorem, proof".  When you figure out what 
"real" means, let me know.

This way of multiplying is isomorphic to what I learned in third grade. 
Multiply these numbers as you were taught. If your numbers have n and m digits, 
below the line in the multiplication there will be n m-digit numbers. (Ignoring 
carries for the sake of exposition), each of those n by m digits corresponds to 
a count of one of the small grids in the Japanese method. Hence the isomorphism.

Carries seem to b handled the same way in both methods.
