Q.3 In a quiz, team A scored -40, 10, 0 and team B scored 10, 0, -40 in three successive rounds. Which team scored more? Can you say that we can add integers in any order?
Answer :

Total score of team A = (-40)+(10)+(0) = -30
Total score of team B = (10) + (0)+(-40)= -30
The scores of both the teams are same i.e. -30. Yes, we can add the integers in any order.
