Answer 1

Explicação passo-a-passo:

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

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

$A-B=\left[\begin{array}{ccc}2&5&4\\-1&-6&-5\\\end{array}\right]$
