How to use this Addition Table:  Pick a number from the top row
(in bold), let's choose 3. )  Pick another number, this time from the left
column (also in bold), let's choose 4. )  From 4, move right until you
find the box that lines up with the 3 in the top row. That box has 7 in
it, this is the answer  3 + 4 = 7.
