This numbers puzzle went viral on Facebook; it's supposedly a puzzle to test your intelligence. The puzzle has a list of equations that seem untrue on the surface, but they all follow one rule that is not identified. These are the equations: 6+4=210, 9+2=711, 8+5=313, 5+2=37, 7+6=113, 9+8=117, 10+6=416, 15+3=1218. Once you have identified the rule that these equations follow, fill in the blanks here: ??+??=123. Watch the video to learn the rule, and see what solutions (hint: there are two!) will solve the puzzle.
