Nobody knows how to think like a dyscalculic at all haha... it's just a little symbol thingy... it doesn't have to be pi. Just like X is a little symbol thingy... the x is now just kind of a table right now...... it's just a little symbol thingy and it means five it's not that difficult. Lmao
Damn inflation is everywhere now, even the transcendentals :'(
Idk, if you want to test people on how they understand formulae and order of operations without letting them just punch it into a calculator. The actual math isn't hard, but if you don't get substituting values into an equation then it's not trivial
Just let π be 3 ...
Or have them learn how to use a calculator at the same time.
Your life is easier and better if you can do this kind of simple math in your head.
Oh don't you try to sell me on the "you won't always have a calculator in your pocket" thing. I have fucking Excel in my pocket.
Who really wants to use Excel to figure out if the 24-pack of Coca-Cola or the 3 12 packs is a better deal?
I don't need to, there's a legal requirement to print prices per liter or kg on every price tag here.
Buy if you want to buy only half a kg, you don't know how much it costs because it only lists the price for a full kg. Do you start pulling out your Excel for that?
Every offer lists how much per kg that offer is. So I do not need any calculations to see which offer is cheaper at all. Why would the price per kilo become useless of I only buy half a Kilo?
Because one is on sale, and they didn't update the sale price. Or, alternatively, because you don't want to be an idiot that can't do basic math.
It's not just about haveing a calculator, it's also that it's faster and more convenient if you can do simple sums like this in your head. It also means you can sanity check the numbers your calculator gives you to make sure you didn't make a mistake entering the sum.
To your point below about products having their unit cost displayed, more than once I've seen that just be wrong, so I wouldn't rely on it. Make sure you can check it in your head.
That's how you know math is OP when you can calculate volumes in parallel worlds where circles don't even looks like circles
They're just rounding up from "3."
And not that pussy rounding up where you go up by only 1, oh no, we’re rounding up 2 baby.
The value of Euler's number is now 4.
With π=5 maths break down completely. If π=5, then e^(5i) = -1, meaning -1 = cos(5) + i * sin(5), or -1 ≈ 0.284 - 0.959 i

Wow, that takes me back - you're referring to the floating point bug from ...98?
665.999999657838 the floating point number of the beast
It's posts like these that makes me think we're all old here on Lemmy and then I get a response from someone who tells me they're 18...
Maybe e is 5, too?
I think you're overthinking it. The first thing you're told when you learn algebra is that a letter represents a number and you can say "let a equal (number), b equal (number)..." so you can let pi equal whatever you want for the purposes of one simple problem.
Or as I like to call pi...the little symbol thingy. But exactly yes, you get it.
But the question is saying to find the volume of a cylinder. Which its clearly wrong.
π = 5 if you round to the nearest 5
The answer is substantially different though. 3141 units (rounded correctly) vs 5000. That's a significant margin that even working it out in your head is not forgiving enough to cover.
Unless I fucked up.
That just means the curvature of spacetime is negative.
Teaching them to to obey dumb instructions from incompetent bosses.
Very useful skill.
Assume the earth is a flat disc . . .
I think I just got it! Pi is very close to 5 dB (~4.9714 dB)
obviously it's inflation index
Pi is now 5 due to inflation
Numbers are symbolic, I’d say it’s not a bad piece of homework to supplement a lesson that numbers are to be respected but ALSO to always know that they mean nothing without context.
We can appreciate the beauty of infinity in memorizing pi, but the reality we live in demands actions of whatever the fuck it is we redefine volition, will, or passion to.
I think people can be so much more, but my idea of more is tainted by the values I have. Not everyone would agree with the idea that we all deserve to live.
Survival of the fittest, they support indirectly. With actions that include the advent of modern advertising. The CIA(?) experiment on attention, catalyzed by the creation of lsd in the knowledge-obtaining-goal of understanding the mechanics of attention, were directly related to the patriot act.
I’m not claiming anything other than the fact that our “leaders,” have used their knowledge of attention spans to sway the, “masses.” The rest of us.
How do you think of the, “rest of us?”
I hope you teach your children that, and that math is the beauty we’ve come to understand in our millennia of evolutionary timescales, of fucking struggle.
You have within you, much.
Do not waste the years of before, do something to help. Not your country, but your reality. The outside. You’re something. Not “nothing but a part of.” There’s so much in the word, “just.”
That’s all I have to say. Just that. Not much. Just a tiny little wall. Sorry. I write, and I rant, and I let go. Please don’t ban me. I matter and I’m not hateful. I’m sorry.
suspension of belief is also being tested, I see.
When you want students to not use calculators but still rate a question for 10 second answer.
π = 5 for very small values of r.
500? But I just woke up and I take sleeping pills so my brain might not be working.
Makes me miss the days of 22/7.
