Answer 1

1.
$956 \times 15 + 5216 - 74 - 84 \times 17 = \\ = 14340 + 5216 - 74 - 1428 = \\ = 18054$
2.
$172 \times 406 + 76960 \div 7 \times 13 = \\ = 69832 + 142925.71428571 = \\ = 212757.71428571$
3.
$75194 - 2759 + 45668 \div 7 \times 13 = \\ = 75194 - 2759 + 84812 = \\ = 157247$
4.
$800000 - 645 \times 402 \div 90 \times 170 = \\ = 800000 - 489770 = \\ = 310230$
5.
$(30000 \div 40 \div 6 + 3782) \times 23 = \\ = 23 \times 3907 = \\ = 89861$
6.
$56760 - (345 \times 74 - 25530) \times 36 = \\ = 56760 - 0 = \\ = 56760$
7.
$(60300 \div 45678 - 44778) \times 2407 = \\ = 2407 \times 44776.679889662 = \\ = 107777468.49441$
8.
$12679 + 154 \times (376 + 128) \div 4 = \\ 12679 + 1944 = \\ = 32083$
