Question

1. Write down a pair of integers whose:
(a) sum is - 7 (b) difference is -10 (c) sum is 0
2. (a) Write a pair of negative integers whose difference gives 8.
(b) Write a negative integer and a positive integer whose sum is -5,
(c) Write a negative integer and a positive integer whose difference
3. In a quiz, team Ascored - 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?
4. Fill in the blanks to make the following statements true:​

Answer 1

Answer:

1 - -12+5

2- -20+10

3- 16-8

Answer 2

Answer:

1. (a) -4 and -3.

  (b) -2 and 8.

  (c) -5 and 5.

2. (a) -8 and -16, as, -8 - (-16) = -8 + 16 = 8.

   (b) -6 and 1, as, -6 + 1 = -5.

   (c) Difference is not mentioned.

3. Points scored by Team A = -40, 10 and 0.

   Points scored by Team B = 10, 0 and -40.

   Total points by Team A = -40 + 10 + 0 = -30.

   Total points by Team B = 10 + 0 + -40 = -30.

   No team scored more, as both's scores were equal.

   Yes, we can say that we can add integers in any order and receive the      

   same sum.
