Title: Edits to Null Values section

1. General editorial work
2. Removed statements about Excel counting as blanks as zeros. It just ignores them like everything else, so SUM(A1:A10) will look like it's treating them as if they were zeros, but AVERAGE(A1:A10) works as expected (it takes the sum of the non-null values and divides by the number of non-null values).
