For example, to solve a system of n equations for n unknowns by performing row operations on the matrix until it is in echelon form, and then solving for each unknown in reverse order, requires n(n+1) / 2 divisions, (2n3 + 3n2 5n)/6 multiplications, and (2n3 + 3n2 5n)/6 subtractions,[8] for a total of approximately 2n3 / 3 operations. The transformation is performed in place, meaning that the original matrix A {displaystyle A} is lost and successively replaced by T {displaystyle T} . Gaussian elimination does not generalize in any simple way to higher order tensors (matrices are array representations of order 2 tensors); even computing the rank of a tensor of order greater than 2 is a difficult problem. To put an n by n matrix into reduced echelon form by row operations, one needs n 3 {displaystyle n^{3}} arithmetic operations; which is approximately 50% more computation steps.[10]. The word "echelon" is used here because one can roughly think of the rows being ranked by their size, with the largest being at the top and the smallest being at the bottom.
