In a quiz competition, team A scored +30, -20, 0 and Team B scored -20,0,+30 in three successive rounds. Which team will win ? Can we say that we can add integers in any order ?

Step 5

Step 6

Total score of Team A = [(+30)+(-20)]+0

= (+10) + 0 = 10

Total score of Team B = [(-20)+0]+(+30)

= -20+30 = +10

Score of Team A = Score of Team B

Yes we say that we can add integers in nay order.
