What is the greatest from 3 integers accepting only positive or above 3 as the greatest number?
If we can only use positive integers or integers greater than or equal to 3, then the greatest number we can choose is 3.
To see why, let's consider three positive integers A, B, and C.
If A, B, and C are all less than 3, then the greatest number we can choose is 2 (since we can't choose 1). But 2 is not greater than or equal to 3.
If one of A, B, and C is equal to 3, then we can choose 3 as the greatest number.
If none of A, B, and C is equal to 3, then the greatest number we can choose is 2 (since we can't choose 1 or 0). But 2 is still not greater than or equal to 3.
Therefore, the greatest number we can choose is 3.
