It is possible to see arithmetic, in example on summation?? Not only a result ?
Not sure that I understand your question... If you mean that you want to see every step of the calculation, then no. Program could only show you a result.

If I want sum 2 diffrent Matrix, in example 2 column/3 verse and 4 column/2 verse is it possible to do this ??
There is no rules in math to do this. Matrices could be summed up only if the number of rows and columns of both matrices are equal.
