7 is weird
this has been driving me kind of mad for a while, but just now i have decided to post on tumblr this rant of mine.
it has the most complex divisibility rule (which is that, to check if a number is divisible by 7, double the unit, subtract the result with the tens unit, e.g. 14 is divisible by 7 because 4 * 2 = 8, which
8 - 1 = 7, which is divisible by 7), it’s a prime number, which already makes it kind of weird, but here it adds onto the weirdness of 7 and finally, most of the numbers which are divisible by it sounds like bullshit, 14, 21, 28, 63 and 70 i can believe, 35 already is kind of making me not comfortable being there, 42 is just bullshit, 49? what the actual fuck, 56’s presence is making me want to congratulate all STEM majors for having to put up with this shit
