        isn't there also 122, 133,221, and all those because it says that no two digit numbers are allowed?

          Thanks for asking!

          I'm assuming that you mean that we should subtract ways like 122 and 223 from the 900 total ways to make a three-digit number.

          The question said that we cannot have numbers that have more than two digits that are the same. So, actually, it's okay to have numbers like 122 and 223 that have just two digits that are the same. The numbers that won't work are the ones that have three digits that are the same, like 111, 222, 333, etc.

          I hope this helps! Please don't hesitate to ask if you have any more questions!

          Happy Learning,
