Which would be the best scientific calculator for examination allowance?

The Casio fx-260 SOLAR Scientific CalculatorCasio fx-115ES PLUS Engineering/Scientific Calculator as well as the Texas Instruments TI-36X Pro Engineering/Scientific Calculator could be used for examination purposes. The models could be chosen according to the functions required.

Which is the best graphing scientific calculator?

The Texas Instruments Nspire CX CAS Graphing Calculator is one of the best graphical calculator, however, it is quite expensive. A cheaper yet close variant would be the Casio FX-991EX Engineering/Scientific Calculator.

Which calculator would be best for domestic use as well as for basic school, college, and business usage?

The answer would be the cheapest and most handy, Casio fx-300MS Scientific Calculator.

What are the common uses of an advanced scientific calculator?

Scientific calculators are typically used for working with scientific numbers and exponents, and for solving trigonometric, logarithmic, and probabilistic problems. More advanced models also allow you to work with hyperbolic functions, inverse functions, degrees, grads, radians, and more. 

Further, you can use the “Exp” button for quicker and easier scientific calculations. This way, you can avoid solving several steps and simply push the “Equals” button to compute the answer.

What is a Ti84 calculator?

The Ti84 is a graphing calculator used in advanced math classes like trigonometry and calculus. It contains all the required functions like log, sine, square root, and more. Plus, one button offers three different functions, and because of this, you may require some practice with a Ti84 calculator to use it to its full potential.

Moreover, using parentheses is essential while calculating complex equations. Even if you’re unsure whether to use one or not, just use it!

Which calculator should a high schooler opt for?

For high schoolers or any student in general, other than offering the required functions, the calculator should also be affordable. Plus, with important examinations like AP, ACT, and SAT, a high schooler would need a device that can reduce the time required for complex calculations. 

As such, a multi-functional and durable Ti84 calculator would be the best bet for high school and college students who want to study smarter, not harder!

What are the different types of scientific calculators?

Graphing Calculators

Mostly used by college students, these calculators are capable of solving complex problems, drawing graphs, and more. Some examples include TI-Nspire CX and Casio Prizm.

Standard Calculators 

Usually the most inexpensive ones in the lot, standard calculators are great for calculating vectors, matrices, etc.

CAS Graphing Calculators

“CAS” implies a computer algebra system, so a CAS graphing calculator is capable of solving algebraic equations. Note that these calculators may not be allowed in most examinations.

What is the difference between C and CE buttons on a calculator?

While basic calculators are much easier to use, they are usually equipped with two similar buttons – C and CE. Some may even use them interchangeably without knowing the functional difference between the two.

Essentially, both buttons are used to clear entries, however, there is a subtle difference. While the C (clear) button clears the entire computation, CE (clear entry) only removes the most recent input.
