In my opinion, Addition to 5 is the fastest but nerve-wrecking since it seems easy to accidently type the wrong number. Addition to 20 is the best, in my opinion, because my right hand gets to move around a bit more and it seems less confined and likely to mess up than just the four possible answers for addition to 5 (2, 3, 4, and 5).

You don't have to use the mouse in Addition to 5 or 20 like you have to with Counting to 100 (just press the enter key to submit your answer).

If you are not good with the keyboard and very good with the mouse, Counting to 100 is possible using mouse only,
