Question

5. In a quiz competetion, Radhika scored -10. 20.0 -20 and Seema scored 0.-30. 10. 20 in four
successive rounds. Who scored more? Can we say that integers can be added in any order?
6. HO = -8 and b = -7, show that a-bb-a.​

Answer 1

Answer:

1) Radhika Scored=

First round = -10

Second round = 20

Third round = 0

Fourth round = -20

Total scored = 20+0+(-10)+(-20)

= 20+(-30)

= -10

2) Seema scored =

First round = 0

Second round = -30

Third round = 10

Fourth round = 20

Total scored = 10+20+(-30)+0

= 10+20+(-30)

= 30+(-30)

= 0

I think seema scored more with 0 score.

I hope it is helpful.
