[@jean-pierrelafaille8713]

After reading this first comment I skipped the "BLAHBLAH" of the author till 4 min. But the BLAHBLAH continued ! So I skipped further, and practically to the end. So I eventually arrived at the end, without having heard/seen ANYTHING interesting ! How can one post such STUPIDITIES ? The matter he "teaches" is material taught in 2nd year of secondary classes, i.e. children of about 13-14 years of age ! That means that people who find this "post" of any interest are of an educational age below this limit ! So, my advice should be to simply suppress this post in order prevent most people losing their time wondering what the author is going to say, and understanding eventually that he says NOTHING !

Hmmm, this is stuff we learned when we were 14 or 15 years old. THe generic form of (X²+Y²)² is (A+B)², for which the standard solution is A² + 2AB + B². Lots of people make mistakes due to stupid discussion on the internet on if either multiplying, substracting, dividing or adding has priority when not using brackets. If you are above 15 and you miss the answer to (x²+y²)², you are in for a big issue as you miss the basics of math which basically you miss the basics of anything that is even closely related to math

[@christianalvarez5409]

I don't even fully understand what you're trying to say in your last sentence, but I can tell you you're being overdramatic. Adults can do well their entire lives without remembering how to solve this problem. You know life exists after high school, right? Unless you're going into a technical field (e.g. engineering), knowing this solution will serve you little to no purpose in life.

[@RealLordy]

@@christianalvarez5409 It kind of depends. I am in engineering indeed. However, I assumed that, when you miss this one, you miss a lot of other basic math things too. This one specifically on itself is indeed not important. But a LOT of math (such as pythagoras, calculating surfaces, and trigonometry in general is very handy for everyone who do stuff at home themselves instead of asking e.g. a timberman or so. Lots of math is "hidden" in thumbrules that those people use, so it is always good to know the background. Is it crucial for life: no, not at all. Lots of things in life are much more important (in my case: my wife and kids happiness come before anything I do :-) ). Does it come in handy: yes. Math always comes in handy, next to being able to speak different languages and know some basics of physics (for which you need math...), or basics of chemistry (for which you need math), or even music (yesyes, also partially based on math: checkout on why classical music is.... classical and the relation of the rhythm to certain mathematical functions :-)) But: I fully understand you and I also fully agree with your answer: math is not at all everything. There are far more important things and it's not crucial. It merely enables you to do some specific things or understand some specific things

[@christianalvarez5409]

@RealLordy you sort of went on a ramble there while missing my point. I'm in engineering as well (chemical). I never said math is unimportant like you are insinuating. Isaid having that exact mathematical equation memorized is unimportant unless you're going into a math-heavy field such as engineering. Otherwise you have no need to have specific equations like that memorized, just general math principles and the ability to look up specific applications as needed.

[@1987slither]

We call that thing ”shortened multiplication formula” and memorize already in primary school. Moreover my teacher would never call that expansion a ”simplification”. Just the opposite.

[@BlacksmithTWD]

@@christianalvarez5409 Your first sentence here is rather problematic though, and probably the cause for the misunderstanding: "I don't even fully understand what you're trying to say in your last sentence, but I can tell you you're being overdramatic." My question is, how can you tell he is being overdramatic while already admitting you don't even fully understand his claim? as the claim you respond to was in the last sentence. Obviously being able to solve (x²+y²)² properly is required for any field that requires more advance math than that. Whether one does it by remembering the mentioned formula or just write it out as (x²+y²) * (x²+y²) and solve it from there doesn't really matter as long as one's method is proper. After all, he didn't claim one is required to use or recall the mentioned formula, the claim was about those not able to get a correct answer to the problem, hence I read the claim as an advice for people above 15 years old who cannot solve this problem to avoid a careers requiring more advanced math. Though even in daily life I encountered enough problems with people who think they can do math but are actually terrible at it. Perhaps next time if you want to make a point, first make sure you properly understand the original claim by asking for elaboration on the claim rather than judging a claim you don't even understand. Otherwise you may just keep arguing about something you already agree upon as if there is a fundamental disagreement rather than a mere misunderstanding.

I have not taught seriously at this level. But I would still make two suggestions. 1.

[@TheToledoTrumpton]

It is the computer age, most of them don't see brackets as a function, merely as an order of operation, They don't like brackets without operators between them, and (a+b) x (a+b) = a(a + b) + b(a + b) , doesn't come naturally when you don't understand that the operation outside the brackets takes priority over the inside of the brackets. So on the Internet, 3 - 4 / 4(1 + 1) is the same as 3 - 4 / 4 x (1 + 1), so the debate is whether it is 3 - 4 / 8, or 3 - 1 * 2, believe it or not! The best way to teach it in the computer age IMO, is to tell them that function( ), calls a subroutine and performs "function" on the contents of the brackets, so when there isn't an operator, you have to do the brackets "function" first and "call" the subroutine as a priority. In that case the brackets are not just an order of operation they are a function.

She now knows the proper way to do it, but if she uses the proper method in school, even though she gets the correct answer, it is counted as wrong.

I graduated from the University of Florida with a degree in Nuclear Engineering in 1986. It was very math intensive. I learned the best method to be sucsesful (sp?) is a little more than notes. First, math text books are books! They are meant to be read. Read the topic to be presented before the lecture and note questions you have. Second, listen to the lecture and get your questions answered. Third, take notes. They are all equal steps. If you read your text book first, you not only have good questions, but it will be the second time the topic is presented. your class mates will appreciate you.

[@programaths]

I had a pupil in remediation and to get her to understand substitution, I asked her to replace letters with shapes. She looked at me with interrogating eyes as if I turned crazy. I did that to break a mental barrier by showing that she can do the substitution blindly. Then I asked her to replace "a" and "b" by two products to break another barrier by showing that one letter can be substituted by an expression. It also introduced the need for parenthesis! Then quite some drill so it became almost an automatism. Yet to see how she will perform of course! It's also why remediation is nice. When teaching, you've to select mental barriers that are the more common, then you can do a little differentiation here and there. In remediation, you can focus on the pupil and analyse his productions to know which mental barrier or bias there is and you can challenge. So, that's night and day ^^

This is almost trivial. Common sense can provide the answer. No need to memorize any "rules" in mathematics as logic and reasoning is all that is required.

That's not a problem of exponents, tho. It's a problem of binomial formulas. Whoever evaluates (a²+b²)² to a⁴+b⁴ will also most likely evaluate (a+b)² to a²+b², which is wrong for the exact same reason. So introducing additional complexity inside the brackets doesn't change a lot here. "99%" will also fail at (sin(a)³+ln(b))², then. Obviously. If you didn't understand the rules of multiplying sums together, you won't be able to multiply sums. Plottwist.

[@wavesAndBerms]

The problem is that you are teaching math as a series of rules to follow. You need to teach principles that provide understanding. So rather than saying that “the rule for (x^m)^n is x^(m*n), you should teach that x^3 = x*x*x. From there it is clear that (x^2)^3 is (x^2)(x^2)(x^2) which is clearly x^6.
