## Homework Statement

Hi guys,

Sorry in advance for posting this type of question in this section as I'm sure it belongs somewhere else, however it technically still is homework for me as I'd really like to be able to get good at this. Personally I've never been great at rearranging equations to solve for any given variable and id just like to know what exactly the steps/rules are (BEDMAS?) when you look at a certain equation and you want to know exactly what to do first? Due to poor teachers in the past few years my basic algebra skill isn't very good and I'd really like to improve it if at all possible. Therefore if any of you guys could give me some insight on what steps to do first when tackling a problem, or could link me a really good resource on this topic I would really appreciate it.

Thanks

## Homework Equations

For example in my math course there is a formula for compound interest: A=P(1+i)^n and I have to solve for n. I just wouldn't know how to really do this.

## The Attempt at a Solution

A=P(1+i)^n

A/P=(1+i)^n - Are you even allowed to do this first??

ln(A/P)=n(ln(1+i))

n=ln(A/P)/ln(1+i)

Can someone tell me if this is correct or terribly wrong?

Thanks
