Hopefully You Have Just "Bought" In To The Idea That Math Logic Has Value!

Please Read This
An essential feature of an ecommerce site is that the site be dynamic in nature. A dynamic ecommerce site offering features such as rapid updates from a database when products change, the ability for customers to search through products matching specific characteristics, as well as other features that require use of a scripting language such as PHP.  Unless one has the skills to program such code themselves, they must hire a tech person at hourly rates that can exceed $75 per hour.

This demo toy store, on a small scale, illustrates those features. The computer code used for this 24 product demo store would be exactly the same if the store consisted of 24,000 products.

The if-then logic used in producing the code to run this mock store is the same used to construct a mathematical proof. See this typical delta-epsilon proof that uses this definition of the limit from a first semester calculus course.

In Summary
Mastering mathematical logic used in proving theorems will help you to properly structure statements used in PHP code and other languages such as ASP used in ecommerce data feed driven sites. It is no wonder that Bill Gates, founder of Microsoft, stated "America's young people must come to see science and math degrees as key to opportunity."
