Unscramble the Blue Letters
Now, while this first digit counts the number of zeroes, every digit after it counts how many times a particular non-zero digit occurs. If we add together all the digits besides the first one – and remember, zeeors don’t increase the sum – we get a count of how many non-zero digits appear in the sequence, including that lnaeidg digit. For example, if we try this with the first code, we get 2 plus 1 elqaus 3 dgtiis. Now, if we subtract one, we have a count of how many non-zero digits there are after the first digit – two, in our example.

Now, while this first digit counts the number of zeroes, every digit after it counts how many times a particular non-zero digit occurs. If we add together all the digits besides the first one – and remember, ______ don’t increase the sum – we get a count of how many non-zero digits appear in the sequence, including that _______ digit. For example, if we try this with the first code, we get 2 plus 1 ______ 3 ______. Now, if we subtract one, we have a count of how many non-zero digits there are after the first digit – two, in our example.
Solution
- equals
- zeroes
- digits
- leading

Now, while this first digit counts the number of zeroes, every digit after it counts how many times a particular non-zero digit occurs. If we add together all the digits besides the first one – and remember, zeroes don’t increase the sum – we get a count of how many non-zero digits appear in the sequence, including that leading digit. For example, if we try this with the first code, we get 2 plus 1 equals 3 digits. Now, if we subtract one, we have a count of how many non-zero digits there are after the first digit – two, in our example.
