If @ is a binary operation defined as the difference between an integer n and the product of n and 5, then what is the largest positive integer n such that the outcome of the binary operation of n is less than 12?  Choose the correct choice from the following: A) 1 B) 2 C) 3 D) 4 E) 5
@(n) = 5n - n   We need to find the largest positive integer such that 5n - n &lt; 12.   Then 4n &lt; 12 and n &lt; 3.   The largest possible integer is n = 2.   The answer is 2.
