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

Answer:

scores of team A = -40+10+0\ =\ -30−40+10+0 = −30

scores of team B = 10+0-40\ =-3010+0−40 =−30

thus, scores of both the teams are same.

commutative property says that a+b\ =\ b+aa+b = b+a

Answer 2

Answer:

Total score of team - A=  -30

Team B= -30

Step-by-step explanation:

Team A scored - 40, 10, 0

Total score = -40 + 10+ 0

= -30

Team B scored = 10,0, -40

Total score- 10 + 0 + (-40)

= -30

So, yes integers can be added in any order
