"Fun fact: A 100-sided polygon is known as a hectogon or a hectagon. Also my mic is so powerful that it picks up my inner thoughts. 😆 #math #mathtok #circle #polygon #geometry"

"Prime numbers are awesome. Also every prime number larger than X can be expressed as either 6n+1 or 6n-1. However the converse is false meaning if a number larger than X can be expressed as 6n+1 or 6n-1 then it may or may not be prime. So we unfortunately cannot use this as a primality test. It's still pretty neat though. #math #mathtok #prime #primenumbers #proof #numbertheory #didyouknow #learnontiktok #mathwithholden"

"The Euler line is yet another idea in math that is named after the great Swiss mathematician Leonhard Euler. The Euler line of a triangle will always contain the circumcenter the orthocenter and the centroid of the triangle for any non-equilateral triangle. And if the triangle is isosceles but not equilateral then the incenter of the triangle will also lie on the Euler line. Incenters are shall we say a bit more stubborn than the other centers of a triangle. 😆 Anyway I think it's so cool that these three points of concurrency the circumcenter the orthocenter and the centroid will always lie"

"If the lighting looks different in this video it's because this was filmed during the Chicago Dust Storm of 2025. 😆 Anyway the biggest ick in all of mathematics has got to be the quadratic formula. It's such an eyesore and it's so unwieldy to use. The more elegant way to solve quadratic equations is the method developed by Professor Po-Shen Loh of Carnegie Mellon University. His method nicely synthesizes ideas that are usually taught separately like the graph of a quadratic function and factoring using a difference of squares. Note: The explanation given in the video is how I chose to"

"What is the value of X - X + X - X + X - X + . Is it X X 1/2 🤔 This sum is known as Grandi's series and it's an example of a divergent infinite series where its sum doesn't exist. However there's a sense in which its value is 1/2 la analytic continuation. Anyway always tread carefully whenever infinity enters the room #math #mathtok #infinity #sum #analysis Background music: "Ultimate Comedy Music Vol. 4" by Sascha Ende (ende.app/en).

"Here is yet another mathematical coincidence for your consideration. Is there something going on between pi and e that we don't know about 👀 #math #maths #mathtok #pi #coincidence"
