What are the functions of the calculator? I believe children all understand that a calculator is a tool for running calculations. Yes, the function of a calculator is to calculate addition, subtraction, multiplication and division. Are there any other functions besides these functions? The answer is yes, so what other auxiliary functions does the calculator have? The following is an analysis of different calculators.
In general, the most common household calculators only have calculation functions and do not have any complicated functions. This kind of calculators are generally used by households to calculate some simple pure addition, subtraction, multiplication and division operations.
For the calculator used in teaching, the function is relatively powerful, not only can calculate addition, subtraction, multiplication and division, but also almost all kinds of mathematical operations can be calculated. Such a function calculator is generally used by teachers and students for those who are more cumbersome. For calculations, such powerful functions are hardly used in daily life.
In addition to these two categories, I believe you have also seen some calculators with alarm functions. Of course, in addition to calculation functions, there are also alarm functions. These are all auxiliary functions. There is no detailed description here.
This is the function of all calculators. The calculator is now an indispensable tool in our lives. Such a small but practical tool, I believe everyone can use it correctly.
