FutureStarrAA Calculator With Percent Sign App
The Calculator With Percent Sign app is a simple mathematics tool that allows you to input an amount and have it calculate the answer as a percent based on the selected number of decimal digits. We all need an in-app calculator and this one’s perfect!
²In my limited experiments, it appears that no two manufacturers of pocket calculators handle the percent key in exactly the same way. Casio appears to handle it in a manner closest to the engineering way. TI is closer to the layman algorithm. And when you get into cases like
The term ‘per cent’ means ‘out of a hundred’. In mathematics, percentages are used like fractions and decimals, as ways to describe parts of a whole. When you are using percentages, the whole is considered to be made up of a hundred equal parts. The symbol % is used to show that a number is a percentage, and less commonly the abbreviation ‘pct’ may be used. (Source: www.skillsyouneed.com)
When you use the percentage key, your calculator quickly multiplies one number by a second number to get a product. By using the percent key, the calculator then takes this product and divides it by 100 to create a new second number. The calculator then completes your original computation (adding, subtracting or multiplying) to give you the final answer.
Add up the number of other cells, and take them from 100. There is one red cell, two green, five blue, 25 purple, and 50 yellow. That adds up to 83. 100−83 = 17. Again, out of 100 cells, 17 are white, or 17%. (Source: www.skillsyouneed.com)
