  It is one of the best on the market (note that it is prohibited in exams). It performs symbolic calculations, as well as numerical calculations, and quite quickly. Derivatives, integrals, differential equations, matrices (eigenvalues, eigenvectors, LU, QR, scaling, but not Jordan), distributions and inverse distributions (e.g. normal distribution and inverse normal), Taylor series, limits, etc. It makes graphical representations (Cartesian, polar, parametric, scatter plot) and 3D (Cartesian and biparametric), although the 3D ones did not satisfy me. It is quite user-friendly, has a system with a mouse and keyboard, but does not have a touch screen. It is also rechargeable. Copy-paste is easy, and there is also an undo feature. It has its own programming language, and from what I understand, there are many ready-made programs available on the internet (e.g. it does not have Laplace transformation, but with the appropriate program, it can be done). The important thing is that you can create projects. For example, you can program it to solve a differential equation using the Euler method, save the results in matrices, and easily view them with a scatter plot, all in the same project, which consists of multiple pages. Everything in this calculator communicates with each other and can be used in the same project.
