For the Given Matrix A:

Does this mean I just multiply al numbers by themselves? As in First Column First Row * First Column First Row (1*1)? Which is ofcourse equivalent to 1^2.
Please confirm if this is correct or not.

That's not right.
The 1st element of A*A is (1*1) + (2*2) + (3*2)
|11 4 4|
|2 5 4|
|4 4 7|
is A*A
