Financial Mathematics Made Easy

Model real decisions: borrowing, investing, and comparing options.

Financial mathematics comes up when you model real-world decision-making: how much you pay for a loan, how returns grow over time, and how to compare options using interest rate logic.

Common Quantities

  • Principal: the initial amount.
  • Interest rate: how quickly money grows or costs accumulate.
  • Time (periods): the number of compounding intervals.

Exam Strategy

Before calculating, translate words into variables. Then check units (years vs months) and whether compounding is periodic. Finally, interpret your result in plain English.
