Idea

[Curious144]

Hi, I am new to this forum but have been following it behind-the-scenes for a while. I have an idea that I need help executing my only challenge is that I am not an excel wizard, at least not yet. But without going too deep into the idea itself, what would be the most efficient way to remove several sets of numbers from a list?
