But his arms are making a triangle.

With angles that need to be found…

I think it’s that new competitor, or is that threads?

My rule for Voice memos is that I only use them if we are both using them. Then it becomes alot of fun.

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

Yeah but the way you derive the order of operations is way above the average maths student.

I say that, but its not really that complicated to derive, since you think in terms of the expansion of the naturals to the reals

My brain is fucking dumb

Metric is based in such a way that the idea is ease of unit conversion.

In base 4 multiplying by 4 would change the unit to kilo or whatever. That would be metric but base 4.

We use base 10, you can argue about the validity of using base 10 but it bears no effect on the metric system. And yes arguements about bases exist.

Base 12 Base 6 Base 60 are all common suggestions. But base 10 is what we are probably are going to be stuck with for a very long time.

The Lemmy DM is imo actually quite important. If I want to get in touch with someone about a post, nothing more. It is an easy option, and serves a purpose. It isn’t imo meant to be used for anything else.
