This study focused on the subject of scientific Application and specifically investigates the applicability of software solutions to Basic ordinary level Mathematics and Physics modeling problems that can be perceived in terms of several independent variables and one dependent variable. From a mathematical perspective, mathematics is the science (or group of related sciences) dealing with the logic of quantity and shape and arrangement, and physics is the ~cience of matter and energy and their interactions. Ordinary level basic Mathematics and physics are one of the subjects being taught in the secondary schools globally. Although teaching is done but obtaining model solution in many areas of interest, often Ordinary level (0-Level) calculations can comprise long and complex calculations that are difficult to solve manually and are time consuming. While some applications can tolerate delays, some applications have been programmed to address specific needs of users, but there remain a significant lot of problem in areas that are yet to be programmed. Because of the above, this Research Report was deemed necessary with the following objectives, to develop a scientific application that will solve some of the following ordinary level basic calculation topics. In Mathematics Matrices, Simultaneous Equations, Linear equations, Cubic equations, Area and Physics Mechanics, Modern physics, Heat, Waves, Current and Electricity. The researcher conducted document analysis as a secondary data collection method. Contributions of simultaneous equations in their respective areas of mathematics and Physics as modeling today were relevant to guide the researcher towards the objectives of the study, and the sources of Internet. As the literature stated, the researcher used document analysis to come up with out put of the research. They were some constraints identified during the process of coming up with what the researcher hard to come up with like Access of the documents e.g. books as the copies were few in the library, internet access was problem, printing and computers (Laptop)
