Much better, but still missing "than" after "greater", which seems kind of critical.
"Using" is important as a number greater than ten can't be written as a digit, but can be written using digits ("with" would be just as good). Repeating "written" makes it clearer that there are two instructions.
It's funny, I didn't notice the missing "than" until much later. After I learned the intended meaning of the original sentence, my mind just seemed to insert the missing "than" automatically.
Mine as well. After understanding the meaning thanks to the other posters, the sentence magically looked fine. But before knowing the meaning, it was gibberish. I’ve become aware of this before, and it makes me wonder just how often I’m interpreting grammatical nonsense on a daily basis without realizing it.
