Answer 1

Boa tarde !

Quando houver um número encostado do parêntese vamos multiplicar !

( + 9 ) × 2 = + 18

( - 9 ) × 2 = - 18

( + 9 ) × 3 = + 27

( - 9 ) × 3 = - 27

( + 2 ) × 5 = + 10

( - 2 ) × 5 = - 10

( - 1 ) × 10 = - 10

( - 3 ) × 4 = - 12

( - 7 ) × 3 = - 21

( - 100 ) × 0 = 0

( - 1 ) × 101 = - 101

( - 25 ) × 2 = - 50

( + 10 ) × 6 = + 60

( - 1 ) × 9 = - 9

( - 1 ) × 200 = - 200

( + 1 ) × 99 = + 99

( - 3 ) × 3 = - 9

( - 5 ) × 3 = - 15

Um grande abraço !
