For Pi Day 2018 I calculated π by hand using the Chudnovsky algorithm.
https://en.wikipedia.org/wiki/Chudnovsky_algorithm
k = 0
42698672/13591409 = 3.141592|751...
k = 0 and k = 1
42698670.666333435968/13591408.9999997446 = 3.14159265358979|619...
Watch me do the second term working out on my second channel:
See me do the entire final calculation again (without a mistake) on Patreon:

This was my attempt two years ago. Look at how much hair I had!
The Chudnovsky Brothers used their algorithm to be the champion pi calculators of the early 1990s: going from half a billion to four billion digits of pi.
