Application to calculate the solution of equations of linear systems
type: 2 x 2, 3 x 3 or 4 x 4.
It should be widely used to "check results",
because it is essential to know how to do, to solve on paper and
pencil these exercises.
Can be used to correct exercises taught in
schools or colleges, in mathematics or linear algebra
Just select the type of system:
2 x 2, 2 equations and 2 unknowns or
3 x 3, 3 equations and 3 unknowns or
4 x 4, 4 equations and 4 unknowns,
then fill in the blank fields with the coefficients of each equation,
with the results and click on "calculate"! after clicking this button
the system solution set is displayed, if there is a solution,
by means of a message on the screen. A message will appear if
the system has infinite solutions or the system has no solutions.
Ability to solve linear equations with decimal numbers up to 10 houses
up to 9 decimals
It works offline.
No need to do accounts, just fill in the fields and click "Calculate".
Thinking about it is thought why not make an App that makes these accounts for us?
The interface is very friendly.
