Unlike simple interest, which is calculated only on the principal, compound interest is calculated on the principal plus the accumulated interest of previous periods. A method used to estimate the value of

Investment math isn't just about picking one winner; it’s about how assets work together. uses math to construct a "mean-variance" optimized portfolio—essentially finding the "Efficient Frontier" where an investor gets the maximum possible return for a specific level of risk. Why It Matters

Measures how much an investment's return fluctuates around its average. A high standard deviation means higher risk. Portfolio Theory Even small differences in percentage rates

In math, "risk" is often expressed as . Investors use statistical tools to predict the likelihood of an investment's return:
