Thought-Process to Discover Knowledge

Welcome to nubtrek.

Books and other education websites provide "matter-of-fact" knowledge. Instead, nubtrek provides a thought-process to discover knowledge.

In each of the topic, the outline of the thought-process, for that topic, is provided for learners and educators.

### Compound Interest

Compound interest is made easy with the following.

maturity value in n time periods A = P (1+R)^n
=P(1+R)(1+R)(1+R)...n times
Note: R is the (interest rate in percentage)/100.

The interest is calculated on the principal for each of the time period in n. That is, the principal for the second time period is the maturity value of first time period, and so on for subsequent time periods.

Once the above is understood, the equation is easily derived.
