Question

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 we say that we can add integers in any order?

Answer 1

Find the score of each team

Given,

The score of team A in three rounds $=-40,10,0$

The score of team B in three rounds $=10,0,-40$

The total score of team A :

$\Rightarrow -40+10+0=-30$

The total score of team B :

$\Rightarrow 10+0-40=-30$

Yes, we can say that we can add the integers in any order as the sum of $-40,10,0$ and sum of $10,0,-40$ is same.

Hence, the score of both teams is the same and we can add the integers in any order.
