Answer 2

Respuesta:

(-) x (-) = (+)                                                  (-) ÷ (-) = (+)

(-) x (+) = (-)                                                  (-) ÷ (+) = (-)

(+) x (-) = (-)                                                  (+) ÷ (-) = (-)

(+) x (+) = (+)                                                 (+) ÷ (+) = (+)
