 HTML scientific calculator front end tool and back end tools

In this post we learn how to make  calculator form HTML and CSS ,generally 

calculator are two types one is the simple calculator and other is scientific calculator.

simple calculator

a simple calculator only doing some arithmetic function like addition,subtraction,

multiplication ,percentage ,and dividation etc.

scientific calculator

scientific calculator doing arithmetic function also scientific calculator doing

some other function like logarithm, exponential value ,cas ,tan ,and radius and

many more function depending on scientific calculator devices.

front end tool of scientific calculator means what is the structure of calculator and

what type of it front screen where you works and back end tools how to completed 

it operation like  Square root,Percentage,Factorial,Constants (pie, Euler constant, log, base e, log 10 base e),

Exponent log base 2, 10, e,Power Sin, Tan, Cos (enter angle in radians ) etc.
