The Mongolist - Lesson Six: Numbers
Numbers are not too difficult to memorize. Start with one through ten, and get those numbers committed to memory. Then move on to the 10s. When you think about it, although there are 101 numbers represented in the chart above, you only need to commit 20 numbers (0-10, 20, 30, 40, 50, 60, 70, 80, 90, and 100) and a simple rule to memory.
