Step 1: Know what simple interest/compound interest is.

1.1 Simple Interest Review

\(P = principle\)

\(r = interest\)

\(t = time\)

\(SI = p \times r \times t\)

1.2 Compound interest

\(P = principle\)

\(r = interest\)

\(t = time\)

\(p = compounding\ per\ annum\)

\(CI = P(1+\frac{r}{p})^{tp}\)

1.3 E

\(e = (1+\frac{1}{x})^x\)
