Question

A player scores 40 and -20 in a game bringing their total score to 20. The player scored two more times, but their total score does not change. If the last two scores were not zero, describe what the last two scores could possibly be and explain why they did not change the total score?

Answer 1

The last two scores could be 10 and -10. When the player scored 40 and -20, their total score increased from 0 to 20. If they score 10 and -10 again, their total score would remain unchanged at 20 because the positive and negative scores cancel each other out.

Step-by-step explanation:

The last two scores could be 10 and -10. When the player scored 40 and -20, their total score increased from 0 to 20. If they score 10 and -10 again, their total score would remain unchanged at 20 because the positive and negative scores cancel each other out.
