[iOS] Solving Linear Equation PRO ($1.99 to Free)

App Description:
This app solves linear equations step by step and plots the result. All the performed calculations are stored in the history. Just enter m, n or two coordinate points and the equation is solved. The final solution can be shared.

[ What you get ]

- solving logic for different inputs like:

- two points

- one point and slope

- one point and intersection with axis of ordinates

- linear equation and x coordinate

- linear equation and y coordinate

- the input supports decimals and fractions

- plot of the result

- history function that keeps your given inputs

- full solution shown in all necessary steps

- no ads!

[ How to use ]

- there are 6 fields where you can insert any value with a modified keyboard

- m for the slope

- n for the intersection with the axis of ordinates

- x1, y1 and x2, y2 as coordinates for the points

- if you enter 3 or 4 values (depending on the calculation you need) and hit the calculate button, the app switches to the solution page

- when you hit the calculate button without giving enough values, the app marks it as yellow

- when you hit the calculate button with giving invalid values, the app marks it as red

- you can tap and/or swipe to get to the solution or history page

- the history entries can be deleted or put in order manually

- if you click on one history entry, the app will load it to the inputs

- you can delete all history entries by using a button
