did people test Zigzagir's comment before thumbs upping it? It is incorrect. If you were to put one stick as "a" and one stick as "1," they will be the same speed, but if you put one stick as "aa" It will not be axa=1x1=1, the speed of the stick would be 11. so aaa=111. aaaa=1111, and so on. b=2 d=4 e=5 and so one. but for letters like "k," k=11 but kk would not be a speed of 1111, but the speed of 121 (110=11). seriously people...take the time to test things before taking them as fact. The scientific method works wonders here.
