The answers varies by calculator. However, most calculators capable of calculating exponents (such as scientific or graphing calculators) have a button with the symbol^. You can use that button to calculate exponents like this: a^x, where a and x are numbers. For example: 2^2 = 4. And 3^3 = 27.
To find the square root of a number you would use the square root symbol on the calculator, √, then enter the number. Ex.: √25=5.

Example: 1 / 4 x 100 = 25 on a calculator so a quarter is 25 per cent where / is the ÷ symbol on a calculator.
100.85/6 = 16.8083 recurring (that is, 16.8083333...). If the number refers to a unit of currency, don't forget to round to the appropriate number of decimal places and include the appropriate currency symbol.
the divide symbol ---> :
Unless it's a fancy graphing calculator, you don't. When solving an inequality, you need to solve it as an equality, remaining mindful of the proper direction of the inequality symbol after each step.
You can't access a percentage symbol on the calculator. The easiest way to use percents is to simply divide the number by 100. If you insist on using something like a percent symbol, you'll have to use the sub( command in the [2nd][0](Catalog) menu. Supplying sub( with only one argument, i.e. sub(43) will divide the input by 100 automatically.
Key in the dividend (the number to be divided) first to divide on a calculator, then key in the divisor after keying in the 'divided by' symbol.

The square root button on a calculator is normally the button which resembles a 'tick' symbol. Depending on the calculator you will press this before or after entering the number you wish to square root.
