Doing the computations by hand, find the determinant of the matrix A
A <- matrix(c(2, 3, 0, 2, 1, 0, 1, 1, 1, 2, 0, 0, 1, 2, 3, 0, 1, 2, 1, 0, 0, 0, 0, 1, 2), nrow = 5)
A
## [,1] [,2] [,3] [,4] [,5]
## [1,] 2 0 0 0 0
## [2,] 3 1 0 1 0
## [3,] 0 1 1 2 0
## [4,] 2 1 2 1 1
## [5,] 1 2 3 0 2
det(A)
## [1] 2
