Question

how many integer lie between -15 and 15

Answer 1

Firstly, you must know the difference between Natural numbers, whole numbers and Integers.

Natural Numbers: 1,2,3,4.....

Whole Numbers: 0,1,2,3,4......

Integers: .....-3,-2,-1,0,1,2,3.........

Therefore, it is pretty obvious to guess the answer now.

In between -15 and +15 there lies 29 integers. {-14,-13...-1,0,1,2...14}.

Hope the solution is clear to you.
