Answer 2

The sum of integers between -4 and 6 is 9.

Given:

Two integers, -4 and 6.

To Find:

The sum of integers between -4 and 6​.

Solution:

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 = 9

Hence, the sum of integers between -4 and 6 is 9.
