Question

Find the sum of integers between – 4 and 6.
Find the number of integers between - 10 and 8.​

Answer 1

Answer:

we need to find the sum of integers between -4 and 6

Integers are composed of natural numbers along with their additive inverses and 0.

The integers between -4 and 6 are -3, -2, -1, 0, 1, 2, 3, 4, and 5.

The sum of integers between -4 and 6 = (-3) + (-2) + (-1) + 0 + 1 + 2 + 3 + 4 + 5

On re-arranging the terms, we obtain

The sum of integers between -4 and 6 = (-3 + 3) + (-2 + 2) + (-1 + 1) + 0 + 4 + 5 = 0 + 0 + 0 + 0 + 4 + 5 = 9ers, -4 and 6

thereofore the sum of integers between -4 and 6 is 9

in its same way we can find that the sum of the integers between 10 and 8 is 18 ,

i hope it helps
