Answer 1

Respuesta:

$a)9 - ( - 9) = 9 + 9 = 18$

$b)0 - ( - 16) = 0 + 16 = 16$

$c)( - 8) + ( - 20) - ( - 15) = - 28 - ( - 15) = - 28 + 15 = - 13$

$d)8 - ( - 2 ) = 8 + 2 = 10$

$e)( - 3 \times 3) - ( - 2 \times 4) = - 9 - ( - 8) = - 9 + 8 = - 1$

$f)( - 9 \times 6) - ( - 1 \times 3) = - 54 - ( - 3) = - 54 + 3 = - 51$
