My Math Forum I absolutely cannot be taught math by anyone

He claims to not be able to learn the general rules in which math is founded on which enables one to solve equations, such as adding like terms to both sides of the equations, etc, to single out the desired variable, 'x'. Well, doesn't the ability to form sentences rely on a set of rules in which to follow? How in the world is he able to formulate sentences in which he has not either been directly taught. If he has not been taught to use a particular sentence in responce to a particular statement or question, then the ability to manipulate the words and ideas to create a new sentence must be just out of his grasp. Again, I call troll...

shinthriir's has nothing to do with anything. Especially not my problems

as for the brick analogy I am beyond lost in that so reading it does me no good because I read the problem of 4x+13=7x+7. and that was it... I have no idea what this is, why it's being used, where it came from, or why bricks were even brought up to begin with... I cannot follow something I do not know one thing about.

Before I even can begin to understand anything about this I need the following information because your throwing me in the middle of this and I don't even know what the hell I'm looking at or why?

 4x+13=7x+7.I'll use the same brick analogy* as hoempa used. We have a balance (i.e. a scale) and it is staying level--the weight on both sides are the same.
Quote:
 If we take weight off or add weight to either side, the balance will tip, since we no longer have the same weight on both sides. But, if we take off (or put on) the same weight to both sides, the balance stays level.

 We want to know how much a single brick weighs,
OK stop right there before you go on I want you to explain to me where the hell you got the information that you need to know how much much a single brick weighs

Quote:
 but right now, we have 4 bricks on one side, and 7 on the other, along with a bunch of other (1 kg) weights.
How do you know any of this...where are you pulling this information from
And now I stopped reading because so far I have no comprehension to what anything you said means

Re: I absolutely cannot be taught math by anyone

Why are you studying maths? Few people bother with it; why should you?

 I can do basics such as addition, subtraction, multiplication, division.
If so, you are actually doing pretty well. Plenty of people can't.

This was an example, which was roughly based on the absolute value example you gave, but is simpler, since equalities are easier to work with than inequalities.

Typically when such an equation shows up in a math book, it comes along with "solve for x" or "what is the value of x?". x represents some number, and we want to know what number(s) it can possible represent. The central idea is that we want to get x all alone, but we can't just write x on one side of an equality and call it done. There are rules for getting from where we are to where we want to be. "We have to follow the roads", we can't just cut through the trees.

We are solving for x. The brick thing is an analogy-- it's a way to think about the problem and visualize it. The idea is to give us something concrete to work with, since numbers and arbitrarily-named variables are abstract and hard to wrap one's head around at first. Bricks and weights on a balance follow the same rules as numbers in an equation, so it makes a reasonable concrete analogy.

How about this: Take a deep breath and forget about math. Really, forget that we're talking about math at all here. Instead, imagine that you are in this incredibly contrived scenario: you have a balance, on one side you have 4 identical bricks (of unknown weight) and 13 1kg weights. On the other side you have 7 (of the same identical) bricks and 7 1kg weights. Someone holds a gun to your head, and tells you that if you cannot tell him the weight of a brick, he will shoot you. Moreover, if the scale tips in either direction at any time, or you try anything clever like holding the scale steady, he'll shoot you.

I know, I know, it's really contrived, but how would you go about trying not to get shot in this situation?

I'm getting the feeling that you're trying too hard. You're trying to force things into a certain mental framework, and you're trying to rush through things. Slow down, relax, and try to let the metnal framework build itself, with minimal nudging and guiding.

I know I get really emotional and it is hard to think about anything at all, much less long, complicated strings of logical/mathematical thoughts. It sounds like you share a similar problem. I love math and want to teach it. But I am failing. Math is one of the most beautiful things in life, but it is not everything. The most important thing in life is whatever you say it is. Whether you are a genius in math or innumerate, you will eventually die. So what matters? What are you living for? Keep it in perspective.

Just another in a long list of "necro-posts"!
