Question

Which of the following is a type of calculator?
A. Scientific Calculator
B. Financial Calculator
C. Graphing Calculator
D. All of these

Answer 1

Hint: Anything used for making mathematical calculations, in particular a small electronic device with a keyboard and a visual display is called a calculator. A calculator can perform different functions depending upon the reason we are buying it for some calculators can show the value of trigonometric functions, some can be used for getting simple or compound interest and others can be used for drawing the graph of a particular function.

Complete step by step solution:
Scientific Calculator - A scientific calculator is a type of electronic calculator, usually but not always handheld, designed to calculate problems in science, engineering, and mathematics. They have completely replaced slide rules in traditional applications, and are widely used in both education and professional settings. Modern scientific calculators generally have many more features like
1. Scientific Notation
2. Floating point arithmetic
3. logarithmic functions, using both base 10 and base e
4. trigonometric functions
5. exponential functions and roots beyond the square root
6. quick access to constants such as \[\pi \] and e
Financial Calculator - A financial calculator or business calculator is an electronic calculator that performs financial functions commonly needed in business and commerce communities (simple interest, compound interest, cash flow, amortization, conversion, cost/sell/margin, etc.). It has standalone keys for many financial calculations and functions, making such calculations more direct than on standard calculators. It may be user programmable, allowing the user to add functions that the manufacturer has not provided by default.
Graphing Calculator - A graphing calculator (also graphics calculator or graphic display calculator) is a handheld computer that is capable of plotting graphs, solving simultaneous equations, and performing other tasks with variables. Most popular graphing calculators are also programmable and therefore considered to be programmable calculators, allowing the user to create customized programs, typically for scientific, engineering and education applications. Because they have large displays in comparison to standard 4-operation handheld calculators, graphing calculators also typically display several lines of text and calculations at the same time.

Therefore all of these are correct option Hence option D is correct.

Note: In certain contexts such as higher education, scientific calculators have been superseded by graphing calculators, which offer a superset of scientific calculator functionality along with the ability to graph input data and write and store programs for the device. There is also some overlap with the financial calculator market.
