Very nice !
This problem shouldn't be named "Summing digits...." because it is the wrong approach. In the first example you sum numbers because 20 is not a digit. If it was - then it should be sum = 6.
What if there are decimals "I have $3.25 in 4 pockets" ? Should the answer be 7.25 or 32?
I don't understand why this is failing?? Can someone explain? It works in matlab for me
