Im going to be taking calculus soon and I am doing ok in my courses, the one thing i feel i need to work on is the ability to manipulate mathematical formulas (change a variable or 2 to find what i need)
for instance this formula
A=P(1+i)^n
can be re arranged as
P=A/(1+i)^n
also
A/P=(1+i)^n
this is a base i feel wasnt covered well enough in previous grades, its one of the most basic things, yet I am not 100% on it there must be a rulebook somewhere or something that explains what to do to variables/equations once you move them around or manipulate them to find the missing items.
Its ironic that i can do just about anything and yet i have trouble with such a simple concept, as i said I am about to take calc pretty soon and i have no trouble with the concepts and material studied so far.
I also believe this skill is needed in physics as well, any help or reference would be appreciated :)
