Answer 1

fill in the blanks

a.25 + (-10) = 25 + (-10)

b. (-49) + 49 = 0

c.14 + [ (-15) + 8 ] = [ 8 + (-15) ]+ 14

d.(-32) + (-21) = (-21) + (-32)

e.100 + 0 = 100

answer the following questions

a.

i.-4 and -5

ii.-9 and -2

iii. 2and -1

iv.2and -1

v.-5and -4

vi. -3 and 2

b.(refer the answer from the picture)

since, integer consists of positive and negative numbers therefore it is closed under addition and substraction.

c.

2000 - (-1878+878)

=2000 - (-1000)

= 1000

d.

shot done by A =6 - 2 - 1 + 5 + 3 - 1

=> (6 + 5 + 3) - (2 + 1 + 1)

=> 14 - 4

=>10

shots done by B= -3 + 3 - 3 + 6 + 5 - 2

=>(3 + 6 + 5) - ( 3 + 3 + 2)

=> 14 - 8

=> 6

therefore, A scored 4 more shots than B.
