Please read this section of Wikipedia which talks about these topics better than I could. It shows that there is ambiguity in the order of operations and that for especially niche cases there is not a universally accepted order of operations when dealing with mixed division and multiplication. It addresses everything you’ve mentioned.
https://en.wikipedia.org/wiki/Order_of_operations#Mixed_division_and_multiplication
There is no universal convention for interpreting an expression containing both division denoted by ‘÷’ and multiplication denoted by ‘×’. Proposed conventions include assigning the operations equal precedence and evaluating them from left to right, or equivalently treating division as multiplication by the reciprocal and then evaluating in any order;[10] evaluating all multiplications first followed by divisions from left to right; or eschewing such expressions and instead always disambiguating them by explicit parentheses.[11]
Beyond primary education, the symbol ‘÷’ for division is seldom used, but is replaced by the use of algebraic fractions,[12] typically written vertically with the numerator stacked above the denominator – which makes grouping explicit and unambiguous – but sometimes written inline using the slash or solidus symbol ‘/’.[13]
Multiplication denoted by juxtaposition (also known as implied multiplication) creates a visual unit and is often given higher precedence than most other operations. In academic literature, when inline fractions are combined with implied multiplication without explicit parentheses, the multiplication is conventionally interpreted as having higher precedence than division, so that e.g. 1 / 2n is interpreted to mean 1 / (2 · n) rather than (1 / 2) · n.[2][10][14][15] For instance, the manuscript submission instructions for the Physical Review journals directly state that multiplication has precedence over division,[16] and this is also the convention observed in physics textbooks such as the Course of Theoretical Physics by Landau and Lifshitz[c] and mathematics textbooks such as Concrete Mathematics by Graham, Knuth, and Patashnik.[17] However, some authors recommend against expressions such as a / bc, preferring the explicit use of parenthesis a / (bc).[3]
More complicated cases are more ambiguous. For instance, the notation 1 / 2π(a + b) could plausibly mean either 1 / [2π · (a + b)] or [1 / (2π)] · (a + b).[18] Sometimes interpretation depends on context. The Physical Review submission instructions recommend against expressions of the form a / b / c; more explicit expressions (a / b) / c or a / (b / c) are unambiguous.[16]
6÷2(1+2) is interpreted as 6÷(2×(1+2)) by a fx-82MS (upper), and (6÷2)×(1+2) by a TI-83 Plus calculator (lower), respectively.This ambiguity has been the subject of Internet memes such as “8 ÷ 2(2 + 2)”, for which there are two conflicting interpretations: 8 ÷ [2 · (2 + 2)] = 1 and (8 ÷ 2) · (2 + 2) = 16.[15][19] Mathematics education researcher Hung-Hsi Wu points out that “one never gets a computation of this type in real life”, and calls such contrived examples “a kind of Gotcha! parlor game designed to trap an unsuspecting person by phrasing it in terms of a set of unreasonably convoluted rules”.[12]

51·1 day agoI’m not saying I like AI images or think people should use them more often, I’m saying in this context I don’t this a disclaimer is needed. If the only problem is “I don’t like AI images because they’re bad” just down vote or suggest to community moderators and/or instance moderators to ban AI images.

Top does not imply dominance. It implies giving/penetrating.
If a selling point was drastically redesigned UX I might give it a go. I hate how much the menus force you to wait in the game. Going to islands is a pain. That dumbass bird’s dialogue takes FOREVER. Letting multiple people join your island at once would be nice too. The method to buy items and clothes is so slow. Let me buy that shit more quickly. Let me craft shit more quickly. Little things like that are the worst.
Also, having more things to do in multiplayer would be good. Like some mini games or something. You can sort of make your own but it’s so minor. Running around pitfalls can only be so fun.
Another killer feature would be letting us make outdoor buildings, but I doubt they’d do something that involved.

42·3 days agoForgejo has all that, and then you can achieve “federation” by virtue of pushing to whatever remote. I wasn’t suggesting people use git itself (which is possible). I just meant that it’s distributed as opposed to centralized like Subverison is.
