А) 68 - 19 = (68 + 1) - (19 + 1) = 69 - 20 = 49
б) 35- 18 = (35+ 2)-(18+ 2) = 37-20= 17
в) 65- 17 = (65 + 3)-(17 + 3) = 68-20 = 48
г) 47 - 29 = (47 + 1) - (29 + 1) = 48 - 30 = 18
д) 302 - 99 = (302 + 1) - (99 + 1) = 303 - 100 = 203
е) 134 - 98 = (134 + 2) - (98 + 2) = 136 - 100 = 36
ж) 200 - 97 = (200 + 3)- (97 + 3) = 203 - 100 = 103
з) 132 -96 = (132 + 4) -(96+4)= 136- 100 = 36
и) 649- 199 = (649+ 1)-(199+ 1) = 650-200 = 450
к) 606 - 399 = (606 + 1) - (399 + 1) = 607 - 400 = 307
л) 370 - 298 = (370 + 2) - (298 + 2) = 372 - 300 = 72
м) 793 - 495 = (793 + 5) - (495 + 5) = 798 - 500 = 298
