  1. This is how I do it. I also used the joints on my fingers to add up when I was a kid so I could add up numbers up to 30 instead of just 10 . I also got into the habit of when adding a number say 7 just add 10 and then take away 3 which is the difference between 7 and 10. Plus I learned all complementary numbers up to a hundred. This all started from counting on fingers. Do teachers encourage kids to do this at beginning school these days? There should be no calculators in elementary and junior schools.
