The math operation made easy with the unit most of the calculation are made in like subtract,add,multiply,divide. More complex calculation can be done in a calculator like calculus and some models do have facility to draw complex functional graphs. They are found everywhere now theyare also found in smartphones and in computers.
Types of Calculators:
Pocket calculator – It is one which can be carried in pocket and it helps people doing athematic. moat of the pocket calculator is powered by solar strips or cells. They are mostly used in offices,schools and business center and can be used to solve complex mathematicalproblems.
Scientific calculators: They are used in exponents function like trigonometry, rations percentages these calculators can solve most of the bigger number some of them are designed as per the pocket size too. One can make programs and upload to computer too.
Internal workings: Some more types have additional display unit with a printer attached which has printer roll in it and full-fledged printing mechanism is attached to the system. There is a process chip which is also present which is linked to the integrated circuit. The components embedded in the design are power source, key pad, display panel and whole working runs with an integrated circuit which is the main functioning aspect of the design.
Power source: Now a days the designs have come up with dual power source in which solar and batteries are provided if the batteries are exhausted one can continuously use it with solar power strips. The main power source of the calculator is solar cells, solar strips, batteries and some old models with main power sources. Usually, all the designs are provided with on and off button to save the power.
Display: Many types of symbols are embedded with functions and commands to make more completed calculations to be done. The complex calculations can also be performed in the calculator with the buttons having the functional ability. A normal calculator has a liquid crystalline display they keys are designed large in the size to that it improves readability and decimal separator is uses instead of the fractions.
Memory: The basic calculator normally stores numbers one at a time and more specific designs store variables which carry the complex calculations. Some are designed to store on the computer also. The new designs have come up with array indexes which can store more memory. Now a days the designs have come out with memory facility in which number and calculations can be stored.
Summing up:
The math operation made easy with the unit most of the calculation are made in like subtract,add,multiply, divide. They are found everywhere now theyare also found in smartphones and in computers.
