The calculator is used for professional use and education use also. The feature is the same in computer Calculator and basic Calculator. Basic Calculations are performed in a programming language like java, python, C++, javascript, etc…. The calculator is used to storing the program and write the program. Calculators are available to store the program. They used to calculate the algebraic expression automatically calculation will be done. The calculator is considered excellent which is used to store and manipulate the graphical programs. Algebra, spreadsheets, databases are also used to perform calculations. Algebra systems manipulate the multiple Calculations and spreadsheets are not called calculators because they only organize the row and column. The database can specify a field name. Non-numerical tools include life-style and scientific calculator. Love Calculate gives the two inputs and **tip calculator ** the percentage and compatibility of these two names. Formula weight Calculator gives chemical molecular formula, this formula is used to calculate by using periodic table symbols and notation. Tip calculation also performed at a high level but every country has the tip calculation it must in us. Various from countries to countries. In that, they won’t provide the tip to the police officer and dentist. And then it also calculates the taxes and total bills.

**High-performance function**

Casio’s BASIC programming language is an easy way to solve the problem. It cannot give the program but it Calculates only to Calculate. The programming language is not to learn the program and many programming languages also used to calculate the problem easily and efficiently. It also clears the complex problems. Casio and Ti program as the same in basic. The LCD is also hight quality is various from the calculator to calculators. Basic Calculator is doing the small operation and a scientific calculator is used to high performance in arithmetic calculations and a graphing calculator is used to plot the graph is in high performance. It calculates the loss price and gains the price of the original price in high performance. It can do the calculation even in decimal points also. The performance equation is done by calculating the three ratios. The performance equation has 3 factors first is CI clock time and CPI clock per instruction and IT instructions count. It is used to calculate the execution time of a problem.

**Pros and cons of the calculator**

The calculator can save time. It reduces the stress on complex problems. Easy way to learn the arithmetic calculations and quickly. It is used to enhance the programming knowledge which is used to solve the problem. The calculation looks very easy and small but programs are used to solve the calculation perfectly. The calculator is used to perform accurately; it doesn’t make mistakes. Calculators are useful in one way but also difficult in other ways that can perform the calculation within magic but students cannot understand what performance is done in the problem. In exam manually students should calculate they won’t allow the calculation in government exams. Calculators are expensive. Students can handle the problem most efficiently but after using the calculator they choose the hardest formula to solve the problem. Students won’t know what was done in the problem. Some devices are costly and become waste once it breaks down. It cannot reuse the calculator. Students are used to completing the task and setting budgets and taxes for their lifetime.
