Very helpful but how do we determine which columns are pivots. What is the criteria for pivots?

What is the definition of a pivot? I have a reduced row echelon form of a matrix that has a '1' at the top row and all zeros in its column but its not a leading entry can we call that column a pivot column?

How to find determinant by using this method?

[PackSciences]

This is the method for humans. A computer will use Gauss-Jordan's algorithm will take the highest absolute value of a row as a pivot.
