Вычисли удобным способом:
(14 + 67) + 3
1 + (99 + 452)
(53 + 96) + 4
(25 + 136) + 75
592 + (85 + 108)
(37 + 207) + 463
12 + 14 + 16 + 18
(290 + 53) + (47 + 10)
75 + (137 + 25 + 63)
(14 + 67) + 3 = 14 + (67 + 3) = 14 + 70 = 84
1 + (99 + 452) = (1 + 99) + 452 = 100 + 452 = 552
(53 + 96) + 4 = 53 + (96 + 4) = 53 + 100 = 153
(25 + 136) + 75 = (25 + 75) + 136 = 100 + 136 = 236
592 + (85 + 108) = (592 + 108) + 85 = 700 + 85 = 785
(37 + 207) + 463 = (37 + 463) + 207 = 500 + 207 = 707
12 + 14 + 16 + 18 = (12 + 18) + (14 + 16) = 30 + 30 = 60
(290 + 53) + (47 + 10) = (290 + 10) + (53 + 47) = 300 + 100 = 400
75 + (137 + 25 + 63) = (75 + 25) + (137 + 63) = 100 + 200 = 300
