The base number in numerology for all of these letters would also be 5. Add 1+4 and you get 5, add 2 + 3 and you get 5 again. 3 directions that all add to 5. Now consider this there are five different styles of yo-yoing but there are only three different kinds of yo-yo to use for all five. Three yo-yos to start with but five levels to attain to.
