At Annie's home cooked chicken wing restaurant, chicken wings are served by the bucket. The biggest bucket of wings is really big. Lets see how many wings are in it. If the wings are removed two at a time, one wing will be left. If the wings are removed three at a time, two wings will be left. If they're removed four, five, or six at a time, three, four, and five will be left. If the wings are removed seven at a time, no wings will be left. What's the smallest amount of wings that could be in the bucket?
