and
(c) Write a negative integer and a positive integer whose difference is -3:

(__)(___),
)(),
_), (
__)and (​

Answer 1

Answer:

a) (-25)-(-30)= 5. Therefore (-25) and (-30) are the two negative integers whose difference is 5.

b)(-4)+2=-2.Therefore, (-4) and (2) are the negative and positive integer whose sum is -2.

c)(-1)-(2)=-3. Therefore, (-1) and (2) are the negative and positive integer whose sum is -3.

d)(3,-1),(-9,3),(12,-4),(15,-5)
