Which of the following statement is not true?
integers are closed under division
whole numbers are not closed under subtraction
whole numbers are closed under addition
natural numbers are closed under multiplication

integers are closed under division

Step-by-step explanation:

Integers are not closed under division.Let us consider two integers i and j.

Then need not necessarily be an integer. For example, 2 and 3 are integers but is not an integer. So the first option , namely, integers are closed under division is not true.

On the other hand, the remaining three options given are correct.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.
