Решение:

1. \( 136 + 30 - 78 - 4524 : 13 = 166 - 78 - 348 = 88 - 348 = -260 \)


2. \( 204 + 73 - 50 - 7912 : 43 = 277 - 50 - 184 = 227 - 184 = 43 \)


3. \( (7102 - 6238) : 54 + 7 - 681 : 21 = 864 : 54 + 7 - 32.43 \approx 16 + 7 - 32.43 = 23 - 32.43 = -9.43 \)


4. \( (6412 - 5308) : 24 + 5 \cdot 872 : 20 = 1104 : 24 + 4360 : 20 = 46 + 218 = 264 \)


5. \( 506 - 42 : 7 - 2958 : 29 - 3 = 506 - 6 - 102 - 3 = 500 - 102 - 3 = 398 - 3 = 395 \)


6. \( 840 - 91 : 13 - 3618 : 18 \cdot 8 = 840 - 7 - 201 \cdot 8 = 833 - 1608 = -775 \)


7. \( 31 - 184 + 156730 : (568 - 548) : 70 = 31 - 184 + 156730 : 20 : 70 = 31 - 184 + 7836.5 : 70 \approx 31 - 184 + 111.95 \approx -153 + 111.95 = -41.05 \)


8. \( 27 \cdot 106 + 120600 : (364 - 339) : 60 = 2862 + 120600 : 25 : 60 = 2862 + 4824 : 60 = 2862 + 80.4 = 2942.4 \)


9. \( (72405 - 13420) : 251 + 29 - 354 = 58985 : 251 + 29 - 354 \approx 235 + 29 - 354 = 264 - 354 = -90 \)


10. \( (69321 - 27426) : 133 + 68 - 184 = 41895 : 133 + 68 - 184 \approx 315 + 68 - 184 = 383 - 184 = 199 \)


11. \( ( (11781 + 507) : 48 + 424 ) - 53 = (12288 : 48 + 424) - 53 = (256 + 424) - 53 = 680 - 53 = 627 \)


12. \( ( (37936 + 292) : 38 + 509 ) \cdot 24 = ( 38228 : 38 + 509 ) \cdot 24 = ( 1006 + 509 ) \cdot 24 = 1515 \cdot 24 = 36360 \)


13. \( 9301 - (273 + 119) - 22 : 28 = 9301 - 392 - 0.7857 \approx 8909 - 0.7857 = 8908.2143 \)


14. \( 804 - (396 + 288) \cdot 35 : 76 = 804 - 684 \cdot 35 : 76 = 804 - 23940 : 76 = 804 - 315 = 489 \)


15. \( 27972 - (512 - 489) : 444 + 968 = 27972 - 23 : 444 + 968 \approx 27972 - 0.0518 + 968 = 28940 - 0.0518 = 28939.9482 \)


16. \( 65424 - (723 - 692) : 464 + 836 = 65424 - 31 : 464 + 836 \approx 65424 - 0.0668 + 836 = 66260 - 0.0668 = 66259.9332 \)


17. \( 24598 : 49 - (135 - 44) - 32302 = 502 - 91 - 32302 = 411 - 32302 = -31891 \)


18. \( 38988 : 57 - (129 - 32) - 17045 = 684 - 97 - 17045 = 587 - 17045 = -16458 \)
