Răspuns:

$495 \div 5 + 129 \times 4 + 2 \div 3 \times 3 - 127 \times 6 - 2 \times 29 = \\ 99 + 516 + 2 - 762 - 58 = \\ - 203$

$4 \times 129 \times 3 - (621 \div 3 - 108 \div 9) - 300 \div 4 = \\ 1548 - (207 - 12 - 75) = \\ 1548 - 120 = \\ 1428$

$144 \div 3 \times 9 - (56 \times 8 - 97 \times 4) + 824 \div 4 + 39 \times 4 = \\ 432 - 60 + 206 + 156 = \\ 734$

$(543 \div 9 - 97 \times 4) \div 5 + (651 \div 3 + 3 \times 128 + 400 \div 100) \\ \div 5 = \\ (61 + 19) \div 5 + (217 + 384 + 4) \div 5 = \\ 70 \div 5 + 605 \div 5 = \\ 14 + 121 = \\ 135$

$252 \div 6 + (435 \div 5 + 14 + 129 \times 3) = \\ 42 + (87 + 14 + 387) = \\ 42 + 488 = \\ 536$

$1 + (70 5 \div 5 + 381 \div 3 \times 2) \div 5 + 576 \div 9 = \\ 1 + (141 + 254) \div 5 - 64 = \\ 1 + 79 - 64 = \\ 80 - 64 = \\ 16$
