The calculator is an electronic device that is used to calculate mathematics and with some other features. They offer a button for on and off like a power button, some Calculator does not offer a button instead of that they may offer some way to off the calculator. A scientific calculator is also a type of calculator in an electronic calculator, but it can’t be handle always it is designed to solve a problem on science, engineering, and mathematics. They have slide rule to complete replacement in traditional applications, it is used in professional settings and education, it is used to two in one process. In professional **tipping calculator ** are necessary. Graphic calculators are used in higher education scientific calculator which is converted according to the content or certain content. It works along with the ability of graphics along with the scientific calculator input data and stored in the program device.

**History of calculator**

In 1968 Hewlett Packard HP 9100A, this was the first scientific calculator which include all the basic programmable such as addition, subtraction, multiplication, and Division. Later Wang LOCL -2 along with Mathatronic Mathatron with the scientific calculator design they add some features. The first calculator based on reserve Polish notation (RPN) entry, with the series Hp-1900, was built entirely for scientific calculator from discrete transistor logic without integrated circuits, CORDIC it was the first use of the algorithm for trigonometric computation, with the personal computing device. RPN and HP become closely identified from that it was developed and developing from today it has some high end. HP-12c has a particular for long-lived calculator or financial calculators and the same time HP-48 series used for the graphics, still offer (RPN) reserve polish notation as for their deft input mode because to having garnered a very large following for this type of calculator. From February 1, 1962, Hewlett Packard was the introduce the packet calculator and scientific calculator as world-first handle scientific calculator, HP desktop calculator is used as Reserve policy notation and some others. Later US$ 395 and H0 -35 were introduced and it was available from1972 to 1975. Several units of the scientific calculator (notion) introduced and used packet or handle scientific calculator were introduced as Texas instrument(IT) on January b15, 1974 in the form of SR-50. In the market, the Texas instrument was run a wide and the most widely used calculator in the classroom with the series in TI -30.

**Use of scientific calculator**

They require quick and access to certain Mathematics or professional function for this widely used a scientific calculator, especially trigonometric function or logarithmic these were once locked in the mathematical tables. In some aspects like very large or very small numbers of calculations in some methods in astronomy, physics, and chemistry. From the junior level to higher education or College education calculator was widely used and also in professional, they used a calculator for easy access. Someplace permit are required to use standard calculator, and also sold in college markets to cover the subject like maths and science, As a result, the high-end calculator is used to solving a textbook calculation and easy to translate on a particular input.
