Do you think math is something that we decide/invent?
Many of the things that might look esoteric or hard to understand often do have some non-abstract meaning/application. “Imaginary” numbers are a good example - they have applications in electrical engineering and can be understood to represent phases/rotation. (Although those weirdos use a “j” instead of an “i”)
Unless you’re doing extremely high level math - like doctoral level - I can guarantee you there is some application.
I agree. But if you’ve ever tried to calculate phase shift with imaginary numbers on something that also represents an electrical circuit. Mixing up j and i even if technically they should be easy to keep apart, gets annoying very fast xD
Feel free to indicate the imaginary unit with ‘X’ or some other distinct symbol during your derivations.
Yes. Reasons: A, B, and C. Not D.
I always thought C was the reason not to while D was in favour.
D was favoured by the New School of Revisionists, who seem to be publishing less and less as their theorems fall flat in the face of the ABC coalition’s triumphs.
It’s just a fad, do not buy into their D-based propaganda
Abstract in what way?
In understanding,so math should always reflect what it can do irl. An example,if i look at a math problem without understanding it i should be able to know what it does irl.
But that’s already how math is taught. Examples, word problems, discussion of applications. It helps students grasp the concepts to know their purpose and use.
That literally seems like a you problem… If you don’t understand math, it’s not math’s responsibility to change because plenty of people do understand math.
If I understand, I think your question can be rephrased as, “Should all concepts be presented so anyone can understand it?” To that version I would say yes, but it requires the person attempting understanding to have sufficient background.
Nah, even arithmetic doesn’t align with the physical world. “Real life math” stopped being useful somewhere in the bronze age.
Math is probably the least abstract concept in existence. There is nothing else as consistent as math.
It’s not math’s fault if you don’t understand the language.
No. Math isn’t just doing sums, or other numeric operations. Math is the application of logic to solve problems. Part of what you should be learning, is how to break complex problems into more manageable steps and then solving those steps to solve the overall problem. And this skill carries well into lots of other areas of life, even those that don’t seem immediately “math-y”.
Abstract is what math is. Try to take away all abstraction, then no math is left.
Practical examples etc. are just nice accessories for learning it at first, but they are not math.

Do you mean math classes/teaching? At school or university? Or just ‘mathematics’ as a concept? It’s pretty hard to be less abstract, when the basic idea of maths is abstraction.
