7/7
Note:University people teach things like Complex numbers, Matrix multiplication, etc, NOT order of operations - that is taught in High School (I've never seen a HS teacher get these questions wrong). If you wanna know about a topic, then ask a person who teaches that topic!
IM summary: Terms can be bracketed, so they are resolved at "B" with TDL, may include an exponent, resolved by "E", but either way fully resolved before "M", so people treating them both as IM already missed the boat! TBC

1/6 #MathsMonday 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...
