Yeah your education failed you. What I am effectively doing is “factoring” 17*18 into (10+7)(10+8), before working out the parentheses, but it’s easier because you only work with numbers and not with x’s. A nice in-between step towards algebra.
- Comment on Cheers Bro 1 week ago:
You need both. Take 1718. Your understanding of multiplication should tell you that this equals 1010+107+108+8*7. Now your rote learning will allow you to calculate this quickly as 100+70+80+56=306.
- Comment on Cheers Bro 1 week ago:
I think your example with the multiplication tables is a great one. It is important for students to have a understanding of what multiplication is both as a building block of more complex math, and because multiplication is one of the most practical skills we learn in school. Having said that, rote learning of multiplication tables is also a useful skill. By learning the multiplication tables you free up cognitive resources when learning something more complex.

I guess that greatly depends on your teacher. However, I will say that “doing the numbers” and understanding are pretty strongly correlated in math. BTW the same goes for English literature where reading more books greatly increases your understanding.

Yes, that’s why social media should I.) allow downvoting, ii.) use an algorithm that reduces the prominence of downvoted posts and iii.) actively remove bot accounts that attempt to game the voting system. Most social media do none of these things, and in fact push controversial takes.
- Comment on oopsie 1 week ago:
Agreed. On most social media websites the sorting algorithm is equivalent to sorting Lemmy/Reddit on controversial. Still I do think there are active parties on Reddit pushing rage bait, and it’s a problem that Hot instead of Best is the standard sorting algorithm on Reddit.

When we think cost of living we mostly think about rent and cost of food. The rich don’t pay rent and food is a tiny fraction of their budget, so obviously they don’t complain.

The death penalty has not been executed in NY/federal court for decades right? Doesn’t seem like an actual threat. What they want to achieve is a good negotiating position for a plea bargain because they known a trial will be a shitshow.

That doesn’t make any sense. Was he faking it? This opens so many questions!

This already started with the Vietnam war, where France warned the US not to get involved. There’s a lesson here but I can’t quite put my finger on it.

I do! I usually buy an annual supply in the Netherlands because it is much cheaper than in other European countries. No alarms were ever raised (obviously since otc pharmacies are entirely anonymous). Again, the price difference between countries gives a strong indication of the profit motive involved.
The argument about blisters sounds ridiculous. Do you really believe you will stop an addict from his addiction because he has to push a bit harder.
- Comment on Het Pijnstillersparadijs: Europese Zelfbeheersing vs. Amerikaanse Pillenfeest 2 months ago:
How exactly do small packages limit use? There is no limit to the amount of packages you can buy. However, those small packages are severely overpriced. I think it’s safe to say that profit considerations played a role in their design.

I have never heard of this in the context of ibuprofen. I know it’s bad on the stomach which means you shouldn’t take it for long periods of time (unless prescribed by a doctor). However, when the source of the pain disappears it’s pretty easy to kick the habit. Very different from opioids that are addictive beyond their painkilling ability.
Also between European countries the price of otc painkillers differs tremendously, and my impression is that European pharmacies generally only sell small packages in an effort to maximise profits.

I really really hope that they will enact their economic agenda before their racist agenda. When they denaturalize and deport citizens, half of us will be cheering (unfortunately). When the price of electronics/ cars increases it distributes harm to all.

If men only date women below 30 (or 27 apparently??) for their youthful appearance, what incentive do those women have to take dating seriously? Those men won’t stay anyway. This is the main contradiction in incel rhetoric. If you don’t like to look at women past 30, women shouldn’t date you “seriously “ while in their 20s.

I am not sure I follow that. The scale is always relative right? It’s just the zero that’s absolute. But that’s also the case with measuring angles where we do use the degree symbol.

Not (frequently) mowing your lawn is one of the best things you can do for your local bee population. Dandelions and other meadow flowers are great sources of nutrition for them. Obviously, don’t use pesticides either.

The only correct answer for a 101 introduction. It’s an incredible powerful intuition even in contexts where vectors are seemingly used as a list of numbers.

The new model is actually to charge the author a shitton of money (think thousands of dollars) after the paper has been accepted. After it should be accessible through
- Comment on Let π = 5 8 months ago:
I think it’s actually a very interesting question. Pi does not equal 5 in our universe, but perhaps we can think of a meaningful universe where it does? Perhaps some mathematicians/physicists can chime in?
- Comment on How is the hydrogen made? 9 months ago:
I really don’t get why hydrogen remains popular. Hydrogen is significantly less efficient than lithium batteries in storing electricity. There are currently dozens of technologies on the way for improving batteries beyond what’s possible with lithium. So what’s the market potential for green hydrogen again?
