Answer 2

It seems like you've provided a series of mathematical expressions. Let's break them down and calculate the results step by step:

1. 900 - 2.50 + 140 = 1037.50
2. 400 - 90 / 3 - 200 = 120.00
3. 700 - 25.2 + 100 = 774.80
4. 120 - 75 / 3.4 + 65 = 100.44
5. 200 - 80 / 4.5 - 35 = 140.22
6. 108 - 54 / 9.7 + 58 = 158.51
7. 342 / 3564 / 2723 / 3 = 0.000035
8. Finally, 342 / (3564 / (2723 / 3)) = 86.078

Please note that I have assumed the operations to be standard mathematical operations (addition, subtraction, multiplication, and division) based on your input. If there's a specific order of operations you intended, please clarify, and I'll recalculate accordingly.
