Answer 1

Step-by-step explanation:

(a) To arrange these integers in ascending or descending order, first we locate these points on number line.

As we know, if a point or number lies on the right side to the other number, then the number is greater. Then,

Ascending order -7, – 5,0, 5,10

Middle term = 0

Descending order → 10, 5, 0, – 5, – 7

Middle term = 0

Hence, zero always remains in the middle of the arrangement.
