Comparing to existing software/web applications of same category, OASE is different mainly for three reasons, viz.
Includes Intermediate Steps: Although there are number of software by which we can have the final solution of same type of problems, to help learners of Linear Algebra, OASE solves problems including almost all intermediate steps leading the solution.
Exact Solution: OASE processes fraction/rational Inputs algebraically instead of numerically. Since no rounding off of numbers occur during calculation, OASE always gives exact solution to the problems.
A Different Web Application: There are a few web applications have been being used for the same purpose which follow only the row reduction methods. On the other hand, OASE solves problems directly using directly the definition as well as using row reduction method.
