Given:

In a quiz, team $A$ scored $-40,\ 10,\ 0$ and team $B$ scored $10,\ 0,\ -40$ in three successive rounds. 

To do: 

We have to find which team scored more.

Solution:

Sum of scores of team $A = -40+10+0$

$=-30$

Sum of scores of team $B = 10+0+(-40)$

$= 10-40$

$=-30$

So, the score of team $A =$ the score of team $B$

Yes, we can say that we can add integers in any order. It will give the same result.
