18.(27·19+19·114:38)= 32273-4-5061-13-2541:21= (13542+47324)-(19308:12)= 48.(18·406+3933:19)= 81-117-25725:25+19347= 9035+(19017-9687):3·18= 817-(327+402)-11564:98= 2.(4·125·8)+(5·4·12·27):18= 3.18.(12152:56+188282= 10881:27+9891:(3528:56)= (560735+3265):1000+509.33= (24480:8+214)+1002-46-48409=

Решение:

1. \( 18 \cdot (27 \cdot 19 + 19 \cdot 114 : 38) = 18 \cdot (513 + 19 \cdot 3) = 18 \cdot (513 + 57) = 18 \cdot 570 = 10260 \)
2. \( 32273 - 4 - 5061 - 13 - 2541 : 21 = 32273 - 4 - 5061 - 13 - 121 = 27074 \)
3. \( (13542 + 47324) - (19308 : 12) = 60866 - 1609 = 59257 \)
4. \( 48 \cdot (18 \cdot 406 + 3933 : 19) = 48 \cdot (7308 + 207) = 48 \cdot 7515 = 360720 \)
5. \( 81 - 117 - 25725 : 25 + 19347 = 81 - 117 - 1029 + 19347 = 18282 \)
6. \( 9035 + (19017 - 9687) : 3 \cdot 18 = 9035 + 9330 : 3 \cdot 18 = 9035 + 3110 \cdot 18 = 9035 + 55980 = 65015 \)
7. \( 817 - (327 + 402) - 11564 : 98 = 817 - 729 - 118 = 88 - 118 = -30 \)
8. \( 2 \cdot (4 \cdot 125 \cdot 8) + (5 \cdot 4 \cdot 12 \cdot 27) : 18 = 2 \cdot (4000) + (2160) : 18 = 8000 + 120 = 8120 \)
9. \( 3 \cdot 18 \cdot (12152 : 56 + 188282) = 54 \cdot (217 + 188282) = 54 \cdot 188499 = 10178946 \)
10. \( 10881 : 27 + 9891 : (3528 : 56) = 403 + 9891 : 63 = 403 + 157 = 560 \)
11. \( (560735 + 3265) : 1000 + 509 \cdot 33 = 564000 : 1000 + 16797 = 564 + 16797 = 17361 \)
12. \( (24480 : 8 + 214) + 1002 - 46 - 48409 = (3060 + 214) + 1002 - 46 - 48409 = 3274 + 1002 - 46 - 48409 = 4276 - 46 - 48409 = 4230 - 48409 = -44179 \)
