Question

in a quiz competition,team A scored-25,10,15,-10 and team B scored 15,0,-30,20in four successive rounds.which team scored more?​

Answer 1

Answer:

Solution 3:

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

so, yes we can add integer in any order due to commulative property.
