Решение:

1. Вычислите:

1. \( 2345090 - 7890 = 2337200 \)
2. \( 87687 + 34242 = 121929 \)
3. \( 6927 - 999 = 5928 \)
4. \( 594847 - 48485 = 546362 \)

2. Вычислите:

1. \( 19 \cdot 19 = 361 \)
2. \( 405 \cdot 111 = 44955 \)
3. \( 23 \cdot 32 = 736 \)
4. \( 123 \cdot 76 = 9348 \)
5. \( 231 \cdot 10 = 2310 \)
6. \( 17 \cdot 883 = 14991 \)

3. Выполните действия:

1. \( 882 : 7 = 126 \)
2. \( 1332 : 36 = 37 \)
3. \( 4816 : 43 = 112 \)
4. \( 173642 : 157 = 1106 \)
5. \( 41121 : 9 = 4569 \)
6. \( 47610 : 69 = 690 \)
7. \( 31749 : 57 = 557 \)

4. Выполните действия:

1. \( 78 + 23 \cdot 81 - 69 = 78 + 1863 - 69 = 1941 - 69 = 1872 \)
2. \( 25(28 \cdot 105+7236:18)-(4247-1823):6 \cdot 25 = 25(2940+402)-(2424):6 \cdot 25 = 25(3342)-404 \cdot 25 = 83550 - 10100 = 73450 \)
3. \( 510 : 17 + 24 \cdot 38 - 80 : 4 = 30 + 912 - 20 = 942 - 20 = 922 \)
4. \( 343 ( 324378 : 54 - 4862 ) + 777 = 343 (6007 - 4862) + 777 = 343(1145) + 777 = 392785 + 777 = 393562 \)
5. \( (120+16 \cdot 7) \cdot 240 : (300 - 5 \cdot 44) = (120+112) \cdot 240 : (300 - 220) = 232 \cdot 240 : 80 = 232 \cdot 3 = 696 \)
6. \( 34 + 27 (43-15) = 34 + 27(28) = 34 + 756 = 790 \)
7. \( 1755 : (724 – 659) + (129-43) \cdot 38 = 1755 : 65 + 86 \cdot 38 = 27 + 3268 = 3295 \)
8. \( (247-189)(69+127) = 58(196) = 11368 \)
9. \( (3967+965) : 9 = 4932 : 9 = 548 \)
10. \( 700700 - 6054(47923 – 47884) – 65548 = 700700 - 6054(39) - 65548 = 700700 - 236106 - 65548 = 464594 - 65548 = 399046 \)
