Sendo A=  \left[\begin{array}{ccc}1&0\\-2&3\\0&4\end{array}\right] e B=  \left[\begin{array}{ccc}5&-3\\1&2\end{array}\right] Calcule AxB:

  \left[\begin{array}{ccc}1.5+0.1&1.-3+0.2\\-2.5+3.1&-2.-3+3.2\\0.5+4.1&0.-3+4.2\end{array}\right]

=  \left[\begin{array}{ccc}5&-3\\-7&12\\4&8\end{array}\right]
esse "amp" nao existe nao sei pq apareceu
o ponto final significa multiplicação 1 x -3 + 0 x 2 = -3
