Pemdas isn’t as arbitrary as people in this thread think it is.
I love maths, and I’m going to butcher any attempt to explain why pemdas isnt totally random. But you can look it up if you wanna know more I guess
Besides no one ever uses that notation - by the time you learn about quadratics, you leave multiplication symbols out of the equation entirely and much of the notation changes shape, with division exclusively being expressed as negative powers or fractions.
At that point you aren’t going to make mistakes, since each hyperlevel uses a different style of notation. Pemdas is used to teach 4 year olds, and it’s fucking dumb. What happens with a log, or sine function. Don’t even get me started on integrals and derivatives.
Pemdas is shit, but not because it’s abirtary. In fact it’s shit because it’s a shithole acyromn
Pemdas is mostly just factoring, kinda. That’s how you should think of it.
2x4 is really 2+2+2+2.
That first 2+(anything else) can’t be acted/operated upon until you’ve resolved more nested operations down to a comparable level.
That’s it. It’s not arbitrary. It’s not magic. It’s just doing similar actions at the same time in a meaningful way. It’s just factoring the activities.
It is, in fact, completely arbitrary. There is no reason why we should read 1+23 as 1 + (23) instead of (1 + 2) * 3 except that it is conventional and having a convention facilitates communication. No, it has nothing to do with set theory or mathematical foundations. It is literally just a notational convention, and not the only one that is still currently used.
Edit: I literally have an MSc in math, but good to see Lemmy is just as much on board with the Dunning-Kruger effect as Reddit.
If you don’t accept adding and subtracting numbers as allowed mathematical transactions, multiplication doesn’t make sense at all. It isn’t arbitrary. It’s fundamental basic accounting.
I come from a Windows and Mac environment and I now happily use Linux Mint. It has a similar aesthetic and is really easy to use. I think not recommending newbies Arch would be a good start.
I agree. Zorin OS is another good option, if people accept the fact that new users don’t care about snaps vs flatpaks. And Zorin OS Pro helps the distro maintainers put food on the table. BTW, its been too long of a wait for Zorin Grid
Indeed, and it runs great on this old machine. I recently made the switch to Wayland from X11 wms like spectrwm and herbstluftwm. The difference is like that old movie, “The Wizard of OZ”, where everything goes from being in B&W, to suddenly technocolor. ;-P
Since the correct mathematical answer isn’t one of the options, the people picking the other options are representing a real resistance to the order of mathematical logic that binds us.
The real answer is 14 because I’m 14 and this is deep.
I did that many times with my game engine, and every time I have had to postpone a release by at least two weeks: one week of implementing the feature, one week of debugging it. (Where can I find people who want to work on an open source game engine?)
And it wasn’t just a 4KB “stick” of RAM or something, it was literally magnetic rings threaded onto wires called Magentic Core Memory. Further, 4 KB implies that it was 4096 bytes, but it was actually 2048 “words” consisting of 15-bits (+1 parity bit) [source]. 2048 words requiring 16 bits each means 32,768 magnetic rings weaved onto tiny wires. Oh, and another fun detail about magnetic core memory is that if you read a value, I.e check to see if one of those magnetic rings is set to 0 or 1, that is a destructive operation. So if you wanted to read without deleting, you have to read and then immediately rewrite.
Tilix [gnunn1.github.io/tilix-web/] is missing from the list. My terminal of choice for the last (I lost count) however many years. Integrates nicely with gnome3+
