    I'm not quite sure how you're supposed to put in the answer, since before the answer box they have A =, but we can still work it out together :)

    Okay, so do you know Newton's 3rd law? For every action, there is an opposite and equal reaction?

    Awesome! That's kind of what we have to do here, except using math. So if we add on one side, what will we do to get that addition to the other side of the equation?

    Now, for this equation, we want to isolate \(p*i\), so to do that, we need to do what to the part that is being \(\bf divided\)

    You are making sense, just narrow down and use simple words so I can understand

    \[1-\frac{ 1 }{ (1+i)^n}\] lets look at just the denominator first now lets get a common denominator the first term 1 is just \[\frac{ (1+i)^n }{ (1+i)^n }\] so together \[\frac{ (1+i)^n }{ (1+i)^n }-\frac{ 1 }{ (1+i)^n}\] or \[\frac{ (1+i)^n -1 }{ (1+i)^n }\] now when you multiply p*i by \[(1+i)^n \] in the denominator it cancels and we are left with \[A= \frac{ (p*i)(1+i)^n }{ (1+i)^n -1}\]
