You continue in the same way until you get to an expression involving the determinants of a collection of 1 × 1 matrices, which the definition says are simply the single elements of the matrices. If n is bigger than 3, this process will involve a lot of bytes (or paper). But in principle it is possible. The following examples illustrate it.

For example, the coefficient (−1) i+1 of the first term in the first sum is negative if i is even. The first expression in the proposition is called the expansion along the ith row of the matrix; the second expression is called the expansion along the jth column of the matrix. The next example verifies the proposition for an arbitrary 3 × 3 ...
