Life is full of calculations, from using basic calculator for performing simple tasks like additions, division, subtraction and multiplication to using advanced calculating devices to calculate your BMI we are increasingly becoming dependent on these calculation devices.
A simple calculator is nothing by a basic tool that is used for performing any numerical calculation. The fist device that was used to calculate numbers was Abacus which also holds the honor of being the first basic calculator invented by man. Abacus was a simple calculator designed using moving beads attached on wooden frames. To calculate the beads have to be moved up and down. This simple calculator had been in use much before the Arabic numerals were introduced. This basic calculator is still being used by some merchants in Asia especially china to calculate values.
The modern calculating device is a handheld electronic device which is increasingly used by not only merchants for calculating purposes but are also being used students to calculate mathematical equations and for doing other school work. However there has been a constant debate as to whether the school children should be allowed to use simple calculator right from the school days as it has an impact on mental ability of the student to perform even simple calculation.
A simple calculator that is used for calculation essentially consist of 4 parts, an LED display, keypad with 10 digits and four arithmetic functions and some other basic functions as well as a power source. There are advanced scientific calculating devices complete with trigonometric and other scientific functions that are widely being used by engineering and medical students.
Gone are the days of the basic calculator as now there are specialized calculators available to perform very specific operations. Specific simple calculator is available to calculate EMIs for auto loans and mortgages while there are health calculators that are used for calculating your calorie intake or calculate the most fertile period in the month for the females that are planning to conceive.
From basic calculator to much advanced sophisticated devices, these calculating devices have surely helped in making our lives more manageable and simple. |
