The set of integers, Z.
No. The set of integer includes negative integers which are not natural numbers..
Integers are all positive and negative whole numbers, and natural numbers are all positve whole numbers including zero. So, natural numbers is a subset of integers.
No. "Natural numbers" means positive integers - sometimes including zero, but never the negative numbers.
No. Negative whole numbers are not natural numbers.
No. Negative integers are whole numbers but not natural.
No. Natural numbers are a subset of whole numbers. Negative numbers are whole numbers but not natural.

The numbers 1,2,3,... etc are called natural numbers or counting numbers. Integers are the natural numbers plus zero plus the negative ( or opposite ) natural numbers. Why do we need negative natural numbers ? For one thing x + 1 = 0 is an equation whose solution is x = -1. We could not solve this equation if we did not have negative integers. So over history these negative numbers came about as a way to solve certain math problems. The numbers 1,2,3,... etc are called natural numbers or counting numbers.

No. The natural numbers are positive.
No. For two reasons: 1) Negative numbers are not natural numbers 2) All natural numbers are rational numbers but the square root of 6 is an irrational number and thus cannot be a natural number.

even, whole, non-negative numbers. (zero is not a natural number)
