Answer:
a. \left(-12\right)-\left(-20\right)
-12+20\ =8
(b) -10+5\ \ =\ -5
c. -12+9\ =-3
3. scores of team A = -40+10+0\ =\ -30
scores of team B = 10+0-40\ =-30
thus, scores of both the teams are same.
commutative property says that a+b\ =\ b+a
so, yes we can add integer in any order due to commulative property.
