To facilitate the 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 output panel and by moving the pages with your finger to the left and to the right. To make the panel go, slide 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 must enter the known values ​​and the field with the unknown
leave clean Press the "=" key to calculate the unknown. To delete all fields, press the "X" key. Mathematics, algebra and cheat sheet.
