Explicație pas cu pas:
65 +84 +35+44 +56 +16
(65 + 35) + (84 + 16) + (44 + 56) = 100 + 100 + 100 = 300
______________
27 +295 +94 +105+23+ 206
(27 + 23) + (295 + 105) + (94 + 206) = 50 + 400 + 300 = 750
______________
418+315 +99+455 +82 +501
(418 + 82) + (315 + 455) + (99 + 501) = 500 + 770 + 600 = 1870
_______________
2040+1580 +8060+ 5674 +1420
(2040 + 8060) + (1580 + 1420) + 5674 = 10100 + 3000 + 5674 = 18774
