The statement is true. Subtracting two whole numbers might not make a whole number. Its just a result of how we count adding apples and apples always gives you whole numbers as adding apples is equivalent to counting the number of apples in two groups of apples.

Since both are subsets of N then their union will also be a subset of N. Real numbers are closed under addition. Natural number are always closed under enhancement and multiplication.

Indeed any proper subset mathSsubsetNmath of the Natural numbers where math1in Smath is not closed under addition because every Natural number can be reached by repeatedly adding math1math with the exception of mathNsetminus0math if your set of Natural numbers includes zero. Natural numbers are actually closed under addition. For the set of natural numbers addition of two natural numbers will always give another natural number ie a b in mathbbN forall ab in mathbbN.

5As Natural numbers are associative for subtraction. If you add any two if them the result will always be another natural number. A Natural numbers are closed under addition b Whole numbers are closed under addition c Integers are closed under addition d Rational numbers are not closed under addition.
