Integers are closed under division, i.e. for any two integers, a and b, a ÷ b will be an integer. State true or false.
False
Integers are not closed under division, i.e. for any two integers a and b, a ÷ b may or may not be an integer.
Ex: (4) ÷ (- 4) = -1, which is an integer.
While (-1) ÷ 2 = - 0.5, which is not an integer.
Therefore, the given statement is false.
