A, C, and D
Step-by-step explanation:
A. Adding up all the numbers gives you a sum of +1 so this is correct.
B. Day 2 has a score of +3 and Day 4 has a score of +1. The difference between those two is +2, not +4 so this is incorrect.
C. Day 1 has a score of -1 and Day 2 has a score of +3. The difference between those two is +4. The absolute value of +4 is +4 so this is correct.
D. Day 1 has a score of -1 and Day 4 has a score of +1. An additive inverse is a value with an opposite sign. One is positive and the other is negative so this is correct.
