Check list:

  1. Solve problems involving present value \(P = \frac{{x\left( {1 - {{\left( {1 + i} \right)}^{ - n}}} \right)}}{i}\)  and future value \(F = \frac{{x\left( {{{\left( {1 + i} \right)}^n} - 1} \right)}}{i}\) annuities.
  2. Make use of logarithms to calculate the value of \(n\), the time period, in the equations \(A=P(1+i)^n\) or \(A=P(1-i)^n\).
  3. Critically analyse investment and loan options and make informed decisions as to best options(s) (including pyramid schemes).
