Question

(9+1)-40 (2+5)-30 (20+40)-6 (50+40)-8 (6+4) 7 . (20+30)-8​

Answer 1

Пошаговое объяснение:

(9 + 1) - 40 = 10 - 40 = - (40 - 10) = -30

(2 + 5) - 30 = 7 - 30 = - (30 - 7) = -23

(20 + 40) - 6 = 60 - 6 = 54

(50 + 40) - 8 = 90 - 8 = 82

(6 + 4) + 7 = 10 + 7 = 17

(20 + 30) - 8 = 50 - 8 = 42
