Select all statements that are always true.
Correct Answer
(1) \(n \div 1 = n\) for any whole number \(n\)
(2) \(n \div n = 1\) for any nonzero whole number \(n\)
(3) \(n \div 0\) is undefined for any nonzero \(n\)
Explanation
Three are always true. The false one: \(0 \div n = n\) is wrong — zero divided by any nonzero number is 0, not \(n\). So \(0 \div n = 0\) is the correct property.
