A calculator is essentially a device that is specially designed to execute different types of mathematical calculations. Depending on what you want to calculate, you can choose from an extensive range of calculators. Generally, the sizes and designs of calculators vary depending on what they are going to be used for. Some calculators are specifically designed for particular purposes like different businesses or trades whereas others are used for basic mathematical calculations such as multiplication or addition.
From school to finances and work, calculators can be mechanical, electronic, or software or hardware. Usually the modern electronic calculators are digital and small. There are some calculators that are capable of solving fractions along with slopes, parenthesis and even add/subtract with percentages. Presently, there is a whole new range of advanced calculators available for you to choose from.
Electronic Calculator
Electronic calculators are very precise:
Besides being useful, calculators are very powerful too. They are almost 100% precise and run on small batteries. Modern electronic calculators are often small, compact, digital and generally inexpensive devices that can easily perform all basic arithmetic operations. Besides the general purpose calculators, there are also the ones that are specially designed for specific markets. For example, there are scientific calculators that specially focus on some complex operations like statistical, arithmetic and trigonometric calculations.
Additionally, some calculators even have the ability or performing computer algebra. On the other hand, graphing calculators can also be used for graph functions that define the real line or a slightly higher dimensional Euclidean space. Latest electronic calculators are portable than majority of computers.
Casio is one of the major electronic calculators manufacturing company. They have an extensive range of electronic and scientific calculators. You can thus choose the one depending on your requirements. There are also dual power calculators that work on solar energy as well as the battery. So, if you want to perform complex mathematical operations, electronic scientific calculators can be the best solutions.
