Answer 3

Let's solve these arithmetic expressions step by step:

1. 345 + 345 = 690
2. 3 456 + 3 456 = 6912
3. 34 567 + 34 567 = 69134
4. 345 678 + 345 678 = 691356
5. 321 - 123 = 198
6. 4 321 - 1234 = 3087
7. 54 321 - 12 = 54309
8. 345 654 321 - 123 456 = 345530865
9. 12 345 654 321 - 123 456 = 123222197865

So, the results of the arithmetic expressions are:

1. 345 + 345 = 690
2. 3 456 + 3 456 = 6 912
3. 34 567 + 34 567 = 69 134
4. 345 678 + 345 678 = 691 356
5. 321 - 123 = 198
6. 4 321 - 1234 = 3 087
7. 54 321 - 12 = 54 309
8. 345 654 321 - 123 456 = 345 530 865
9. 12 345 654 321 - 123 456 = 123 222 197 865
