Answer 2

It seems like you've written a sequence of mathematical equations. Let's break them down one by one to see if they're correct:

1. $3 + (-18) \div 9 = 7$ This equation is not correct. The correct calculation would be: $3 + (-18) \div 9 = 3 - 2 = 1$

2. $17 - 40 \div 8 = 12$ This equation is not correct. The correct calculation would be: $17 - 40 \div 8 = 17 - 5 = 12$

3. $127 + 2 \times 8 = 143$ This equation is correct. The calculation is: $127 + 2 \times 8 = 127 + 16 = 143$

4. $7 \times 5 + 2 = 37$ This equation is not correct. The correct calculation would be: $7 \times 5 + 2 = 35 + 2 = 37$

It seems like there are errors in the first and second equations. If you intended to express a different set of equations or have specific questions about them, please provide more context or details.
