Hello Ed,

I agree with you. The same symbols for the different operators might be a bit confusing.
Here, just from the result one can conclude what has been used (scalar and matrix result)
minor(vminor(B,2,3),2,2)=1
vminor(vminor(B,2,3),2,2)=mat(1,1,1)
In addition, there might be something like this:
M.23(←B^2
A.23(←B/2
minor(B,2,3)=13vminor(B,2,3)=mat(1,4,-1,9,2,2)M.23(=mat(6,67,104,-2,57,76,15,95,159,3,3)
alg(B,2,3)=-13A.23(=mat(0.5,2,3.5,1.5,0,2.5,-0.5,4.5,5.5,3,3)
Generally, literal index might make confusion as well (especially for the beginners). Fortunately, here is a visual difference between subscripts (additional spaces). However, confusion and errors might be introduced if we are not careful enough. Here is a workaround - we can use something like this in these situations:
minor(B,(2),(3))=13vminor(B,(2),(3))=mat(1,4,-1,9,2,2)alg(B,(3),(3))=-12


Regards,
Radovan
