Concept
You know how to count from 1 to 100 perfectly. 1, 2, 3... 98, 99, 100! But what happens next?
π― The Hundreds Pattern: The number 100 is just a new starting block. You just start counting by ones all over again, but you say the word "One-Hundred" first! * 100. * One-hundred and one (101). * One-hundred and two (102)... * ... One-hundred and ninety-nine (199).
What happens at 199?! You run out of ones. You run out of tens. The Hundreds dial clicks over! * 199 rolls over to -> 200! (Two-Hundred). Then you start all over again. (201, 202...)
