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

$\huge\colorbox{orange}{Solution ࿐❤}$

Team A scored - 40, 10, 0.

Total score = - 40 + 10 + 0 = -30

Team B scored 10, 0, -40.

Total score = 10 + 0 + (-40) = -30 .

The scores of both teams are equal.

Yes, we can add integers in any order. We had observed that the scores obtained by both teams in successive rounds were numerically equal but different in order. Yet, the total score of both teams were equal.

Hope it helps you ❤

Answer 2

Answer:

- 30

Step-by-step explanation:

Team A :-

Total score of Team A

= - 40 + 10 + 0

= - 40 + 10

= - ( 40 - 10 )

= - 30

Team B :-

Total score of Team B

= 10 + 0 + ( - 40 )

= 10 - 40

= - ( - 10 + 40 )

= - ( 40 - 10 )

= - 30

Therefore, Both them score same, - 30

Yes, we can add integers in any order.

Hope it help you.
