Mathematics Problems

This is a math app. Quickly find the answer: in calculations (for example, find the angle COS), in combinatorics (for example, calculate the variation or combination), perform operations with matrices (for example, multiply a matrix by a number), calculate the determinant (for example, find the solution of a second-order matrix), find the derivative and calculate the integral, and solve fractions.

If you want to save the solution, to view the help or capture the solution, press the “Save” button. And if you want to see the saved one, press the file button. If you want to delete all the saves, press the “Delete” button.
Then if you want to clean it, press the “Clean” button.
And to calculate the solution, press the “Calc” button.
Without the upgrade, you can only calculate and use the functions. But there are no restrictions with the upgrade.

You can draw numbers and signs on the screen with a pen or your finger.
