I don't know why I made this video but it demonstrates the use of the colon symbol on most scientific calculators to do stuff with it. Kind of a pain to record (with my phone blowing up from excess heat) and edit (button sequences which absolutely did not need to be there) for something that did not benefit me in any way at all but I still felt like doing it anyways. The pi approximation took really really long to even get anywhere, 3.141... in my case, that my phone overheated and stopped the recording, explaining cuts.
I might die if I found out some button presses were wrong, I couldn't find an error, so I pray hard. Very tedious, waste of time for me, 0/10 will do again.
