In my opinion, the main advantage of the program Office Excel is a huge number of built-in standard functions, which allows you to easily and quickly apply various calculations. Excel has several categories of functions, which greatly simplifies the work. Mathematical and trigonometric functions are used when processing matrices and solving various problems. Logic functions are suitable for solving problems with certain conditions. For my work, I create three shortcuts with commands that automatically perform certain calculations I need. Such programs simplify the work and make it easier, as there is no need to do everything manually.
