Question

Question 65
In the following question, state whether the given statement is true (T) or false (F).
Natural numbers are closed under substraction.

Answer 1

False
Since the difference of any two natural numbers is not always a natural number, they are not closed under subtraction.
Example: 30 - 40 would give a number that is less than zero(or a negative number) which is not a natural number.

Hence the statement is false.
