Advantages and Disadvantages of Calculator

Calculator:
The Calculator is an electronic device used to do basic mathematical calculation. It is been common in day to day life where everyone makes use of its application. In the early stages they perform only the basic operation like addition,subtraction,multiplication and division. A required number of research and assessments are carried out to develop scientific and advanced calculator.

The cost of the calculators varies based on the features, application, size, etc. Learning calculator as a tool is very important for all of us to face the real life problem. The world has faced a tremendous change in the technology, which allows each and everyone to make use of a calculator. Multiple linked representation of a calculator like led,solar, graphing calculator is used in a wide range of application involves both practical and theoretically.

Advantages of Calculator:
The advantage of calculator is more than its disadvantage. To reduce the complexity of solving problems and for quick learning of subject in students, the calculator is allowed to use in schools  and colleges. Accurate counting of a number can be brought out by using calculator. Using a calculators, students become more comfortable with developing  new technology.

Enough number of problem’s can be solved  repeatedly without any difficulty. The option of calculator is found in all electronic application devices. The Simple function calculator is available in all technical model as an application in different variety which are user friendly. Scientific calculator offers a wide range of conversion data. They are advanced version of calculator, which are widely used among higher level students.

Free Online Math Calculator:
Free Online Math calculator is available for fast and easy solving of problems, which helps in saving time for for both students and teachers. Online calculators are free and easy to workout. In the online application the user can make use of available calculator buttons or use the keyboard for the operation. The free online calculator provides advanced terms of calculating  the problem which makes the user

Disadvantages of Calculator:
People find it difficult to do simple calculations without the use of a calculator. Teachers and  Parents are against making use of calculator for lower level class of students because which reduces the basic skill of learning mathematics techniques among them. Logical thought of mind or logical learning skills keeps on reducing day by day. Even though the need of a calculator is essential and used in wide range of application manual method of solving the problem is carried out for verification is carried.

Question:I can't really think of a disadvantage other than if theres no light in the room, the calculator won't work but who would use a calculator in the dark. Eh!? Lol thanks x

Answers:advantage: being able to use the calculator whenever you want without having to worry about the battery life. Disadvantage: When u really need it, it won't work because there is no light.

Question:it's for my college assignment plzzz help me thank you

Answers:advantages: accurate and reduces the work that you have to do disadvantages: the main disadvantage is that it can make you 'lazy' with simple mental arithmetic and can reduce your ability in this area.

Question:Can anyone answer it? I have it as a question for math.

Answers:The advantage is that it can be done mechanically, with no insight or intelligence of any sort, it can be used to find (approximate) solutions for any equation, no matter how complicated (given that even something as simple as a quintic polynomial cannot always have its solutions expressed using a finite number of field operations and root extractions, approximate solutions are sometimes the best you can do), and if being used to check solutions, minimizes the chance of arithmetical error in the verification. It can also be used to assist in the visualization of a function (although cannot replace it, since somtimes a function has irregularities on a scale smaller than the pixels of the graph window). The disadvantages are that since the graphing calculator works numerically rather than symbolically, it sometimes accumulates serious numerical errors from rounding (compare http://img206.imageshack.us/img206/1730/graph1nv6.png with http://img205.imageshack.us/img205/7366/graph2gw6.png -- these two should be the same polynomial, but the second doesn't look like a polynomial at all because of numerical instability in the calculation). Also, it can give misleading solutions (do not EVER try to find the limit of a function using a calculator unless you know before you enter the function what the graph looks like -- I've seen too many students get burned because the behavior of a function changes just outside their graph window, or on a scale too small to see), and frequently can only verify that a solution is correct to within some numerical error -- a verification that the solution is actually exactly correct requires symbolic manipulation. Finally, attempting to use the graphing calculator constantly will lead to the atrophy of symbolic manipulation skills, typically rendering it inappropriate for use in a math class, whose purpose is to develop those skills. This is not to say that the calculator should never be used in math class, but if the students are using it to do mathematics rather than computation, they invariably end up failing in later courses where success is impossible without actual understanding (taken any analysis courses lately?).

Question:

Answers:Science and technology go hand in hand. You could very easily argue that in the whole scheme of things, technology has no disadvantages in advancing science. Technology like the telescope allowed for astronomy to be born, and the microscope in biology. In a way, science (particularly modern science) cannot exist without technology of some kind. If you mean to say information technology or electronic technology, the advantages are clear. Radiology and understanding what's going on inside the body can only be done with x-ray or computerized tomography imaging - all highly dependent on technology. Mapping the Human Genome has been suggested to be entirely a technology problem, but now that we know what the Human Genome is made of, we can perform more scientific research on it. This is a clear example of how technology enables science. Disadvantages are much harder to identify, but one might be a growing dependence on technology, like kids not learning basic math because calculators exist, or that modeling how organisms live on a computer is not a good approximation of what's going on in the real world and could lead to poor-quality science.
