Answer 2

Sure, here are the calculations arranged in a column:

1. 1.04 * 8.5 = 8.84
2. 5.497 * 0.42 = 2.31074
3. 1.25 * 1.6 = 2.00
4. 0.34 + 0.6 = 0.94
5. 0.74 + 3.26 = 4.00
6. 5.29 + 11.1 = 16.39
7. 0.26 - 0.6 = -0.34
8. 31.4 - 29.57 = 1.83
9. 8 - 4.6 = 3.4

I've performed the calculations according to the given expressions. If you have any more questions or need further assistance, feel free to ask!
