Pororo the penguin is playing with numbers! He is given $3$ integers: $A$, $B$, and $C$. He can multiply or add the three numbers in any order, but he wants to get the largest possible result using all three numbers. For example, valid results are $A\times (C+B)$, $(C\times A)+B$, or $A+B+C$. Help him figure out the largest possible result!
