What is the highest number you cannot make with the numbers 6, 9, or 20. Integers obviously. if you don't understand what i am asking, for example, you can't make 14, so which is the largest number you can't make since once you get so high you can make every number. Is there a quick or mathematical way to do this besides brute force and guessing?
