I'm with the right answer here. / and * have same precedence and if you wanted to treat
2(2+2)
as a single unit, you should have written it like(2*(2+2))
.It's pretty common even in academic literature to treat implied multiplication as having higher precedence than explicit multiplication/division. Otherwise an expression like 1 / 2n would have to be interpreted as (1 / 2) * n rather than the more natural 1 / (2 * n).
A lot of this bullshit can be avoided with better notation systems, but calculators tend to be limited in what you can write, so meh. Unless you want to mislead people for the memes, just put parentheses around things.
That's fair. Personally, I just have a grudge against math notation in general. Makes my programmer brain hurt when there's no consistency and a lot of implicit rules.
Then again, I also like Lisp so I'm not exactly without sin.
All the order of operations rules of Maths are explicit
Apparently not.
Yes, it is a Term subject to The Distributive Law, written just the way it is.
