Math question

Furthermore, you could tell your child that if the teacher asks "What is 5 minus 4?", your child could respond, and be correct, by answering ".9 repeating".

Yes. Infact, by adding that repeating, you just changed the value equal to a 1. People say that since its a 9, it will never equal to a 10. I say that since its repeating, there will never be a 9 at the end. By stopping the process, all of this falls apart. 

The infinite of this makes this equal to a 1. Anything less and it will not be.
