We call it *minor minor* relative to an element **The _{ij}** of an array

**M**, square and of order n> 1, the determinant

**MC**, of order n - 1, associated with the matrix obtained from

_{ij }**M**when we suppress the row and column that go through

**The**Let's see how to determine it by the following examples:

_{ij}.a) Given the matrix , order 2, to determine the smallest complement relative to the element **The _{11}(MC_{11})**, we removed row 1 and column 1:

Similarly, the smallest complement relative to the element to be_{12} é:

b) Being , of order 3, we have:
