Answer: -20 is the choice 1
Step-by-step explanation: The given question seems to involve a series of operations on a list of numbers. Let's break it down step by step:
1. -8 - 6: When subtracting a negative number, we can rewrite it as addition. Therefore, -8 - 6 is the same as -8 + (-6). Adding the two negative numbers gives us -14.
2. 00: This seems to be a typo, as 00 is not a valid number. We can ignore it for now.
3. 6: This is a standalone number, and there are no operations given to perform with it.
4. 4: Similarly, this is also a standalone number.
5. -2: Another standalone number with no operations given.
6. -4: Same as above, a standalone number.
7. -6: Again, a standalone number.
8. 8: Yet another standalone number.
9. +: This seems to indicate the start of a new set of operations.
10. -8 - 6 - 4 - 2: This is a subtraction operation. Starting with -8, we subtract 6, then subtract 4, and finally subtract 2. Simplifying this gives us -20.
11. 6: A standalone number.
12. 2: Another standalone number.
13. -2: Also a standalone number.
14. -4: Yet another standalone number.
15. -6: Similarly, a standalone number.
16. -8: One more standalone number.
17. N: It's unclear what this represents, as it's not a valid operation or number. We can ignore it.
18. +: Again, this seems to indicate the start of a new set of operations.
19. 6: A standalone number.
20. 99: Another standalone number.
21. +x: This is an unknown operation. Without further context, we cannot determine its meaning or perform it.
22. 8: A standalone number.
23. -: This indicates a subtraction operation.
Based on the given information, we can perform the following calculations:
-8 - 6 = -14
-8 - 6 - 4 - 2 = -20
