i fixed matrix multiplication notation, you can thank me later 😎😎
@acegikmo your “t”s are on the bottom and “b”s on the left 
s/b/l/g
s/t/b/g
@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
