1917 (part 1) - Left Associativity
I have seen many people who argue about this #Mathematics issue that refer to changes in 1917, and I started to research it this week. The #Maths change I thought was made, I have not been able to find any reference for it, and that is about /2(1+3) vs. /2*(1+3). Apparently in pre-1917 #Math the latter was also considered to be a single term (in the denominator) but now is 2 terms. If anyone has a reference for that then please let me know...

2/6 So first I'll discuss a reference I did find, which relates to a letter from Lennes to The American Mathematical Monthly https://doi.org/10.2307/2972726. There's a lot to unpack, and the TL;DR is no, they did NOT change any rules, and this week I'll talk about left associativity, a mistake that I have seen people make in similar order of operations problems to the ones we have been discussing...
