Today, while we were putting up our numbers for the F2 Drosophila crossings, it came to the attention of some of the students in my class that I write my sevens with a strike in the middle and that my nines look like a handwritten letter g. This initiated a conversation about the Arabic number system and the origins of the writing of the numbers in it. Mr. Choe told us that proper writing of these numbers is related to the number of angles that each number represents. I never knew this was the case but find it really fascinating now that I know about it. Thus, I decided to share this idea with you guys.
