Answer 1

$a) \: (700 - (505 - 135 \times 2 - 38 \times 3) \times 2) = \\ = (700 - (505 - 270 - 114) \times 2) = \\ = (700 - (121 \times 2)) = \\ = 700 - 242 = \\ = 458 \\ b) \: (220 \div 4 + 6) \times 100 - (25 + 68) \times 2 = \\ = (55 + 6) \times 100 - (25 + 68) \times 2 = \\ = 61 \times 100 - 93 \times 2 = \\ = 610 - 186 = \\ = 424 \\ c) \: 1000((250 \div 25 + 330 \div 3) - (30 \times 2 - 5 \times 8)) \times 4 = \\ = 1000(120 - 12) \times 4 = \\ = 1000 \times 108 \times 4 = \\ = 108000 \times 4 = \\ = 432000$
