In most cases you need quite a deep knowledge of the subject before you fully understand where the basics come from, so without explaining to you high GCSE, a level or even degree work just to show you something it was easier to say thatbrumley53 said:My main problem with maths was when everyone else just did things because "Thats what the teacher said" i would usually question them asking how it works and why it does it, they would then politely answer with "It just does". It didnt really help much but I eventually worked out how and why.
I agree that maths is probably the most important invention/discovery, but it's not the only way to understand the universe...Tipsy Giant said:Maths is one of the most important skills there are, mainly because it is the only real language and it is the only way to understand the universe...
These two things are directly related. There are many ways to explain most mathematical concepts, and many schools/teachers/educational systems seem to be fixated or standardized on using ones that aren't terribly good. Many of the teachers don't really understand what they're teaching all that well, either, so they may not even be aware of other ways to teach the concept, much less be able to come up with which one is appropriate for a particular student or class.Ambi said:- Teachers give poor explanations. They seem to confuse explanations with instructions. I think if I'd focussed more on the instructions than being so clouded over with wondering how something works and why it seems to contradict other things I'd learned in maths I'd have done well. "Cancelling out numbers? How can you just do that? How does it just disappear? I don't get it at all."
- They can't envisage the concept. I had an epiphany when I noticed a poster with the Pythagorean theorem in a visual format with the squares coming out of the triangle and the cartoon of Pythagoras. I think I was about fifteen <_<
Just to be pedantic, you're mainly talking about arithmetic. "Real" math at a higher level is actually much more related to logic/reasoning than it is to the plain old arithmetic kids do in school.Even many of the most witty, eloquent, and insightful people I've come across online mention they can't do maths despite being good at verbal reasoning/logic.
I have 0 apples. I owe you 2. That means I have -2 apples. If I owe you twice that, that means I have -4. If I owe 2, 2 times how did I end up with 4 things I didn't have in the first place?Xyliss said:No, you owe me minus 2 lots of apples, which is different to oweing me 2 lots.

The problem is, you don't owe twice as many apples. If you owed 2 apples, and then had twice as much debt, it would be -2 apples times 2, not a -2.Corum1134 said:I have 0 apples. I owe you 2.
