**Welcome to the Universal of Calculator**

In the history of the computer generation, the first computer was invented in the year 1600-1700. In those days, computer was used as a calculator application. Basic calculator operations such as addition, subtraction, multiplication and division involved in the older days computers. Older days computer/calculators machines has located in a large space area. So older calculator consumes lot of space and late response from the output. Day by day calculator application access increased gradually.

**Percentage Calculator**

Percentage Calculator is the calculator where the percentage of given number will be calculated , and percentage rate will be calculated based on the given input and the number

For Example: The percentage: 5% The input: 1000 Then 5% of 1000 is 50

Percentage rate of given value:

For Example: The input: 50 The number/amount: 60 Then 50 is 83.33% of 60

**Volume Calculator**

Volume Calculator is the calculator where the volume of the particular object. The object can be Cube, Cylinder, Cuboid, Triangular, Sphere and so on.

Formula

Volume of Cube: a^{3}, where a is the length of any side of the cube

Volume of Cylinder: 3.14 * r^{2} * h, where r is the radius and h is the height

Volume of Cuboid: l * w * h, where l is the length, w is the weight and h is the height

Volume of Sphere: (4/3) * 3.14 * r^{3}, where r is the radius of the sphere

**Home, Car & Personal Loan Calculator**

Home, Car & Personal loan calculator is the calculator where EMI of the home or car or personal loan based on Loan amount, loan period and Loan interest

Formula:

E = P×r×(1 + r)n/((1 + r)n - 1), where P is the principle, r is the rate of interest and n is the Loan time period

**Interest Calculator**

Interest calculator is the calculator where the interest of the given number wIll be calculated. Interest calculator will mainly used in financial sectors

Formula:

Simple interest:

S = ( r * B * t ) / n, where r is the annual interest rate, B is the balance, t is the time period and n is the interest frequency

Compound interest:

A = P (1 + r/n) (nt), where A is the future value of the investment, r is the rate of interest, P is the principle amount n is the number of times that interest add per year and t is the number of year that interest is invested
