Now you don’t have to rummage through the textbook, the program contains the main algebra formulas needed by students. The calculator next to the formulas finds an unknown value if all the others are known, which helps in solving problems.
For ease of reference, the guide is divided into several sections: abbreviated multiplication, quadratic equation, degrees and roots, logarithms, trigonometry, arithmetic progression, geometric progression and planimetry (triangles, parallelogram, rhombus, trapezoid).
You can select the desired section in the table of contents at the top, in the side exit panel and by flicking the pages with your finger left and right. In order for the panel to leave, swipe from the edge of the screen from left to right. For convenience, the formulas are highlighted.
In the calculator, the fields for entering values are highlighted in yellow. To use it, you need to enter the known values, and the field with the unknown
leave clean. Press the "=" key to calculate the unknown. To clear all fields, press the "X" key. Mathematics, algebra and cheat sheet.
