The question goes as follows:
Given the matrix:
[4 0 -2
-1 -2 3
8 5 1]
What is a_(base)1,2?
Thank you very much.

Are you asking what is  a%5B1%2C2%5D ?

If so,  then  a%5B1%2C2%5D = 0.

It is the element of the matrix in the intersection of the first row  (lower index "1",  the first index)  and the second column  (lower index "2",  the second index).
