Find the determinant of the following matrix. [2 3] [1 4]

=======================================================

Explanation:

For any 2x2 matrix of the form

the determinant is equal to a*d - b*c

We multiply the diagonals and subtract the products.

This determinant formula only works for 2x2 matrices.

In this case,

So we have a*d - b*c = 2*4 - 3*1 = 8 - 3 = 5

The determinant is 5.
