What is in this set

The numbers in this set run from 100 to 99,878.
Every problem in it will come out column by column with nothing carried.
A careful solution takes 5 written steps on average.
The mistake this set invites most often, in 100% of the problems: the two numbers were subtracted instead of added.
Answers are a whole number.

Drawing 240 problems from this page produced 240 different ones, 100% — so a sheet of 20 is a new sheet almost every time.
