What's New in LinearSystemsSolver

LinearSystemsSolver 1.6.7

August 11, 2024

New functionality has been added (Max and Min buttons) to the LP (or linear programming) part of this app. Tapping the Max-button turns the linear program into one that maximizes the objective function and the inequalities (in the constraints) will be less than or equal. Tapping the Min-button turns the program into one that minimizes the objective function and the inequalities will be greater than or equal. Unless one of these buttons has been tapped, the app will not display constraints and the Intercepts and Solve buttons will not function. A white button labelled Max or Min will appear if one of the two buttons has been tapped. That white button acts as a reminder of which button, Max or Min, has been tapped. Its label will be the same as the tapped button (Max or Min).

William’s REVIEW

To : The Developer of the LinearSystemsSolver F. Tessier

As a high school student, linear systems are taught immediately in math. When students are given homework they do not have a good way to check if their answer is correct on their own. Having a Linear Systems calculator app is a wonderful idea that can benefit youth struggling in their studies. Aside from the classroom element, the flexibility of being able to have up to 20 different variables/equations boasts practical applications in the workforce as well. As solving large linear systems proves to be extremely tedious this app will save a lot of time for people and be worth the small $2 investment.

As someone who would like to purchase this software, I would take this chance to recommend a few changes/additions. 1. As the clear button is very easy to press, and it cleanly erases everything, if not an undo button on the key pad, perhaps have the clear button take you to a confirm section to avoid careless slip-ups. 2. Instead of having the instructions on screen permanently, you could have them a button click away thus leaving more room for numbers or extra buttons (undo/history). 3. Finally, it would be nice to be able to hear/watch about how this program actually works. A detailed youtube video would be greatly appreciated.

Thank you for taking the time to read this humble man’s review of LinearSystemsSolver app.

Great for students and academics!

As a student in computer science, I use this app as an aid for studying my math courses and use it to check my answers. Being able to solve linear systems through an app on my phone makes it very convenient because it reduces the hassle of carrying around big bulky graphing calculators and not to mention they can be very expensive! For under a dollar I can do all that on my phone, which I’m guaranteed to carry around daily. This app is simple, easy to use, and very useful!
