A long time ago, we calculated simple addition and subtraction operations through calculations. Multiplication and division operations can only calculate small numbers. Once the numbers become larger, they cannot be calculated accurately. However, the invention of the abacus is already a major advancement in human civilization. With the development of technology, calculators are now the most common computing tool in our lives. So what are the functions of calculators? Below is a brief overview of the calculator.
Calculators are generally divided into two types, one is a household calculator and the other is a scientific calculator. These two calculators play different roles in our lives and have different functions.
The calculation function of the home calculator is relatively simple, and it is very convenient to use. In the home calculator, it supports twelve digits, can calculate arithmetic operations, square roots and simple percentages, and only has the function of one memory.
Scientific calculators play a more important role in teaching and scientific research. They are not as simple as home calculators to use. There are some programs that need to be changed through the mode. The numeric keyboard of scientific calculators does not have the numeric keyboard of home calculators. Larger, the function key is relatively small. Scientific calculators can not only support simple arithmetic operations, but also support those academic functions and binary calculations.
Scientific calculators can also perform some percentage algorithms. These are common algorithms in daily life. It is a very convenient way to use scientific calculators in daily life.
The above is an overview of the calculator.
