This is true if the numeric data is handled exactly by the CAS, but it does not need to be slower if the data is handled numerically.
Experience: uncheck Textbook mode display in Settings.
Enter this in CAS:
a:=ranm(100,100,0..1)
This creates a 100x100 matrix with approx random coeff in 0..1
M0:=a
1/a in CAS takes about 1s
1/M0 in Home takes more time.
