You scored on a game show is -300 you answer the final question correctly,so you win 400 points.what is your final score
Rasek [7]

Answer:

Your score is 100.

Step-by-step explanation:

If you have -300 and add +300 you will end up with 0 because when a positive and a negative that are equal cancel each other out. So if you add +300 to -300 you get 0 but its 400 so 300 + 100 is 400 so you have +100 left. : )
