response: I'm not sure if the common person would know this or not, but the Cham and Khmer version of 7 also looks similar to their form for 1, though not in the same way 7 and 1 look in European text.
original_response: Im not sure about that but  As is the case with the European glyph, the Cham and Khmer glyph for 7 also evolved to look like their glyph for 1
history: Seven's my favorite number, because everyone says it's a lucky number.. but why do they say that! What's the history behind 7 Well, it's the natural number following 6 and preceding 8. Of course... but is there more about it? Why has it been seen as somewhat of a special number throughout history? Anything interesting about it? I really don't know. What I can say, however, is that the Hindus wrote 7 more like an upside-down J. Alright, interesting. Some history there. What else is a fun fact about it? The European form of 7 was influenced by Arab forms, which is a horizontal line at the top joined by a vertical line on the right going down to the left. Oh, that's pretty cool. What's another fact the common person might not know?
knowledge: As is the case with the European glyph, the Cham and Khmer glyph for 7 also evolved to look like their glyph for 1, though in a different way, so they were also concerned with making their 7 more different.
