[2124]+[5113]​

Answer 1

Resposta:

$\left[\begin{array}{ccc}2&1\\2&4\\\end{array}\right] - \left[\begin{array}{ccc}5&1\\1&3\\\end{array}\right] = \left[\begin{array}{ccc}2 -5&1-1\\2-1&4-3\\\end{array}\right] = \left[\begin{array}{ccc}-3&0\\1&1\\\end{array}\right]$

$\left[\begin{array}{ccc}2&1\\2&4\\\end{array}\right] + \left[\begin{array}{ccc}5&1\\1&3\\\end{array}\right] = \left[\begin{array}{ccc}2 +5&1+1\\2+1&4+3\\\end{array}\right] = \left[\begin{array}{ccc}7&2\\3&7\\\end{array}\right]$

Explicação passo-a-passo:

Para realizar uma soma ou subtração de matrizes, basta apenas somar ou subtrair os elementos correspondentes de maneira a formar uma matriz Cij = Aij -/+ Bij
