Now we will give proof of the solution of the quadratic formula. Why? Because we can! We will rewite this equation in the form with in order to be able to easily factorize the whole thing. In order to find the values where the x-axis is crossed has to be…
I have a temporary math tutoring job now, and after not much more than an hour of prepping I stumbled upon the proof of the quadratic formula myself. Never thought that would happen. I’ll write it down in a seperate post. But at least the reasons why the Taiwanese will…
A month or two ago, well I guess three by now, I saw a video like this on my Facebook reels…. ….and it made me wonder about three things. First of all, how does this work?Secondly, what is the general formula for let’s say AA x BC? (Where A, B…
Yeah so I took a well-deserved break from baby-math, because a) I’m a n00b anyway, and b) I wasn’t in the mood for math. It’s not too interesting. So the real symmetry is not between positive and negative ‘numbers’ (whatever they are), but between 0-1 and 1-infinity, and negative numbers…
Yeah so there obviously are numberlines in different bases. Let’s check base 10 first: 0-10-100-1000-10000 etc. 1-9, 10-90, 100-900, 1000-9000 etc. So we can conjecture (obviously it’s true, but hey) that between the ‘first’ and the ‘next’ power of N (10 here) there are N-1 spots that have integers (9…
(Prepare yourself for some really bad math.) I think this is the very final math problem I ever do, because I find it outrageously boring. But I’ll write it down, just for the sake of whatnot. “Infinity” itself seems, as far as I understand, to be poorly understood; and at…
