Incrementation by Six

STEP 1

Just count the numbers on the cycle in both the even cycle (0-6-2-8-4...) and in the odd cycle (1-7-3-9-5...). Know this by heart before you do step 2.

STEP 2

Do first as beginner, then migrate to slow, then medium, and then fast. Keep up in counting along with the graphic progression.
Remember, a 0 means any number that ends in a zero, like 10, or 40 , or 2430. Do both the EVEN and ODD incrementations.
