Вычисли, используя новый вычислительный прием:
54 + 39
67 + 15
28 + 23
42 + 19
36 + 48
57 + 14
18 + 75
26 + 69
54 + 39 = (54 − 1) + (39 + 1) = 53 + 40 = 93
67 + 15 = (67 + 3) + (15 − 3) = 70 + 12 = 82
28 + 23 = (28 + 2) + (28 − 2) = 30 + 26 = 56
42 + 19 = (42 − 1) + (19 + 1) = 41 + 20 = 61
36 + 48 = (36 − 2) + (48 + 2) = 34 + 50 = 84
57 + 14 = (57 + 3) + (14 − 3) = 60 + 11 = 71
18 + 75 = (18 + 2) + (75 − 2) = 20 + 73 = 93
26 + 69 = (26 − 1) + (69 + 1) = 25 + 70 = 75
