Counting numbers are called natural numbers.
Ex: 1, 2, 3, 4, .................
All counting numbers, zero, and negative of counting numbers are called integers.
Ex: ......., -3, -2, -1, 0, 1, 2, 3, .........
Now if we take a number For Ex. -3
It is an integer but not a natural number.
So, all integers can not be natural numbers.
