Why create

INVBAT.COM was created by Apolinario “Sam” Ortega, currently working at Salt River Project (SRP), a community-based, nonprofit utility and one of the nation’s largest public power utilities in Phoenix, Arizona, USA. He works at Electrical Engineering and Asset Optimization department. In his free time at home, he is passionate in pursuing INVBAT.COM since 2009.

He observed that his brain memory recall of mathematical formulas and equation is no longer within five minutes, his personal time limit. So he asked himself these two questions, “What are the available tools that I can use to help me retrieve formulas and equations within five minutes anytime and anywhere?  Is it possible to combine calculator and formula so I can get an answer within one minute? ” His answer is to use the internet to solve the problem of anytime and anywhere. Next he learned the language of internet such as CSS, HTML, HTML5, and JAVASCRIPT to solve his second problem, combining calculator and formula to get an answer within one minute. Then he subscribes to Yahoo web hosting service since April 27, 2009 to implement his solution. Now INVBAT.COM  is migrating to Amazon Web Service  EC2-Linux, EBS and S3 cloud technology in order to serve the growing number of public users.

Sam Ortega  is now confident that he can remember mathematical formulas and equations that he created in INVBAT.COM within five minutes to help him do engineering analysis, design review, and make recommendation. He believes science, technology, engineering, arts, and mathematics (S.T.E.A.M) students, teachers, and employees worldwide will also need help to remember their own formulas and equations. He sees a business opportunity for creating customize calculator with embedded formula for other colleagues in S.T.E.A.M to help them have their own personal formula and calculator website. So  he created his online formula and calculator (ofc) store, , to manage the order and payment processing for students, teachers, and employees who need help to create their own personal formula and calculator website.
