Dziękuje z góry za poprawne odpowiedzi i proszę nie podawać od razu poprawnego wyniku. :D

Answer 1

(-3) x 2 x (-1) x (-2) = -12

(-10) x (-20) x (-3) x (-4) = 2400

(-3) x (-7) x (-5) = -105

(-1) x 2 x (-1) x 2 x (-1) x 2 = -8

(-1) x (-2) x (-3) x (-4) x 5 = 120

Answer 2

( - 3 ) x 2 x ( - 1 ) x ( - 2) = -6 x(-2)= 12

( - 10 ) x ( -20 ) x ( - 3 ) x ( - 4 ) = 200 x 12 = 2400

 ( - 3 ) x ( - 7 ) x ( - 5 ) =21x(-5)= -105

( - 1 ) x 2 x ( - 1 ) x 2 x ( - 1 ) x2=2x(-2)= -4

( - 1 ) x ( - 2 ) x ( - 3 ) x ( - 4) x 5 = 2 x 12 x 5 = 24 x 5 = 120
