Answer: Her final score is negative 1.
Step-by-step explanation:
She started off with a score of 0, then gained 4. So you would add 4 to zero. Then, she lost 8 points so you would subtract 8 from her current score of 4, making the new total negative 4. Last, she gained three more points so you would add 3 to -4, giving you the final answer of -1.
4 - 8 = -4
-4 + 3 = -1
