Digits, loved and hated

Yesterday my 7 year old daughter told me that there are digits she loves, and digits she hates. There are also digits that are so-so.
So, we assigned each digit a score ( -1,0 or 1) and tried to analyse long numbers with those scores.
For example, she says that she loves 5, hates 7 and is OK with 4.
Will she love 5547? ( yes, t0tal score is 1+1+0-1=1)
Will she love 7745474?
And so on.
We had a lot of fun.
You could also make it more complicated introducing scores in between, etc, graphing it and so on.
