Freya Holméri fixed matrix multiplication notation, you can thank me later 😎😎
l'empathie mécanique@acegikmo your “t”s are on the bottom and “b”s on the left 
s/b/l/g
s/t/b/g
@acegikmo so the l’s would be on the left and b’s on the bottom.
also, s/a/x/, so x’s would be on a row/column intersections
@dpwiz what do you mean by s and x?
@acegikmo ‘s are just plural suffix.
x are variables in the middle matrix, that are now a
@dpwiz I'm confused lol, the matrix with all the 'a' is already aligned with the b matrix and the t matrix in terms of the coefficients in the polynomial, that's the point of the tweet
@acegikmo I’m talking about the variable names.
they can be position mnemonics so
the linear form would look like
l0 +
l1x0 + b l1 x1 +
….
This way one can easily sort them out to proper positions in the notation form and collect back to linear.
zl2tod@zl2tod oh, I've never seen this notation before
@acegikmo
I'm going to have to read up on my matrix notation too.
There's an s// example here. Sorry.

Interesting! I think I can see how it might work when all three matrices have multiple rows and columns, but what would it look like if you were multiplying more than three matrices together?
