Răspuns :

816 × 10 - 3 × 125 = 8 160 - 375 = 7 785

________________

444 - 44 × 9 + 13 × 12 = 444 - 396 + 156 = 48 + 156 = 204

________________

(21 + 35) × 107 = 56 × 107 = 5 992

________________

(55 × 44) + (86 × 99) - 123 = 2 420 + 8 514 - 123 = 10 934 - 123 = 10 811

________________

(17 × 6 × 3) + (15 + 37 × 7) × 25 - 342 × 2 = 306 + (15 + 259) × 25 - 684 = 306 + 274 × 25 - 684 = 306 + 6 850 - 684 = 7 156 - 864 = 6 472

________________

(952 × 5 × 1) + 732 × 2 - (2 + 732 + 451) = 4 760 + 1 464 - 1 185 = 6 224 - 1 185 = 5 039
