Hey, i really hope you can help me..

I'v just started going Algebra, but the problem with me is that i lack motivation, and my last test i got an E+ but it wasn't lack of trying. I do Distance Education and i recorded some of my Telephone Lessons, and i have a exercise book full of notes, but i still cannot grasp maths...

My Substitute Teacher left this comment "This shows lack of knowledge and effort"

But it's not true... I'm dyslexic i feel in maths, and well. I'm ashamed to admit it, but last year i could care a tuppance about what happened to me, and i let my friends do it for me and my sister, but now when i really want to learn how to do maths properly and not feel like a dunce... I'v put myself into a sticky situation...

I'm hoping over a period of time, with me using this Forum, you may be able to help me develop my skills

So... I have this Question... I'm doing Algebra 1. And the Question is... Well:

-------------

Old Mrs. Payne once said:

"I was x years old in the year x2" (the 2 is like squared)

When was she born?

How old was she in 1980?

In What year will she be a century?

How old will she be in n years from now.

Then they have this here which i don't quite understand:

The Story so far!

Algebra usespronumerals, that is letters which take the place of numbers. In the puzzle, x represents Mrs. Paynes age, 44.

3x + 4 is anexpressionmade up of 2 terms: 3x and 4. TheCoefficientof x is 3. (How do we know that?)

ab - 5c + 2 has three terms: ab, -5c and 2. The Coefficient of ab is a. (again, how did we find that?)

The Coefficient of c is -5 (where did that come from?)

2x+5=19 is anequation.It always has an equals sign and can usually be solved to find the value of the pronumeral that makes the equation true.

The Conventions used in arithmetic (what is that?) expressions are also used in algebraic expressions, with one exception. In Algebraic expressions the multiplication signs is often omitted.

5 x t may be written 5t (yeah i know that) The numeral is always written first.

a x b may be written ab

1/2 x y or y divided by 2 may be written as y/2

---------------

Okay and then they ask me, to "Write the expression for:" a) the sum of 6 and 7 (b) the sum of n and 5 etc.

HOW DO I UNDERSTAND THIS?
