SUMMARY
This discussion focuses on resources for learning how to rearrange formulas in mathematics, emphasizing the importance of understanding algebraic operations. A recommended resource is the website maths.com, which provides guidance from basic to advanced levels. Participants highlight the challenge of applying learned concepts to complex problems, stressing that mastery requires recognizing how operations can be undone, such as understanding that if $y = x + b$, then $x = y - b$. This foundational understanding is crucial for tackling more difficult mathematical questions.
PREREQUISITES- Basic algebraic operations (addition, subtraction, multiplication, division)
- Understanding of algebraic formulas and expressions
- Familiarity with the concept of rearranging equations
- Problem-solving skills in mathematics
- Explore advanced algebra techniques for rearranging complex formulas
- Study the principles of algebraic manipulation and their applications
- Practice solving higher-level math problems that require formula rearrangement
- Review resources on mathematical reasoning and logic to improve problem-solving skills
Students, educators, and anyone seeking to enhance their understanding of algebraic manipulation and improve their mathematical problem-solving abilities.

well I've found this which is good

the problem I am having throughout my maths module on any subject is this,i can always do the basic examples so easily ,but come the crunch question time the questions are ridiculously hard and seem to be so complex compared to examples that I lose my focus and can compute them in my head

Well, math is a lot like distillation-it takes lots and lots of raw material to squeeze out a precious drop of understanding.
There is "trick" to algebra (this applies to more advanced kinds, too)-you have to understand what a thing DOES, so you can UNDO it.
For example, if $y = x + b$, then $x = y - b$, because "subtraction" undoes "addition". Now this is an "easy" example, because most people are so "used" to adding, that it is "natural" to think of subtracting after adding to "go back".
