matriz A = ![\left[\begin{array}{ccc}0&-3\\1&-2\end{array}\right]](https://tex.z-dn.net/?f=++%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D0%26amp%3B-3%5C%5C1%26amp%3B-2%5Cend%7Barray%7D%5Cright%5D+ "\left[\begin{array}{ccc}0&-3\\1&-2\end{array}\right]")
matriz B = ![\left[\begin{array}{ccc}2&5&\\3&6\end{array}\right]](https://tex.z-dn.net/?f=+++%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D2%26amp%3B5%26amp%3B%5C%5C3%26amp%3B6%5Cend%7Barray%7D%5Cright%5D+ "\left[\begin{array}{ccc}2&5&\\3&6\end{array}\right]")
det(a)= 3
det(b)= -3
Det (A-B)= 0
