Пошаговое объяснение:
а) 37*12 + 37*88 = 37*(12+88) = 37 * 100 = 3700
б) 7*12 + 8*7 = 7*(12+8) = 7 * 20 = 140
в) 37*12 - 37*2 = 37*(12-2) = 37 * 10 = 370
г) 7*102 - 2*7 = 7*(102 - 2) = 7*100 = 700
д) 28*9 + 22*9 = 9*(28 + 22) = 9*50 = 450
е) 25*11 - 25*1 = 25*(11-1) = 25*10 = 250
ж) 18*9 + 18*1 = 18*(9+1) = 18*10 = 180
з) 25*99 + 25 = 25*99 + 25*1 = 25*(99+1) = 25*100 = 2500
и) 101*17 - 17 = 101*17 - 17*1 = 17*(101-1) = 17*100 = 1700
к) 41*50 - 50 = 41*50 - 50*1 = 50(41-1) = 50*40 = 2000
