How to Use a Calculator: 

• Learn the symbols associated with math. Basic calculators are dominated by a few standard symbols including a plus sign (+) for addition problems, a minus sign ( - ) for subtraction, a multiplication symbol (x or * ), a division sign ( ÷ ) and an equal sign ( = )
• Understand the processes that go along with the signs. If you don't understand the process of division, it's useless to know the sign because you won't be able to successfully put it to use. By learning basic math principles, you can then use a calculator to put those processes to work
• Acquaint yourself with the layout of a calculator. Most calculators have numbers in the middle, beginning with zero at the bottom of the layout and working upwards, in rows of three, to the number nine. Basic math symbols are generally placed to the right of the numbers. You'll find the percentage button ( % ) and square root button with the math symbols
• Try a graphing or scientific calculator when you learn more math processes. These calculators perform more difficult mathematical processes and can handle longer strings of numbers. When you learn various formulas and do longer problems, graphing and scientific calculators can do much of the work for you

How to Figure out Percentages:

• Figure the percentage of a particular number. Divide the number by 100 and then multiply by the percentage you want to determine. For instance, if your restaurant bill is $85 and you would like to leave an 18 percent tip, your tip will be $85 / 100 = 85 cents. Multiply 85 cents by 18 (1 percent X 18!) to get your answer: $15.30
• To figure what percentage one number is of another: Multiply the number by 100, then divide by the number you want to compare it with. For example, if your rent is $1,400 and your take home pay is $3,500 per month, you are spending 40 percent of your pay for rent: $1,400 X 100 / $3,500 = 40
• To figure out a sale price of a discounted item, use step one to figure out the dollar amount of the discount, and then subtract it from the original price. For instance, an item with an original price of $134 that is discounted by 25 percent will cost $100.50.The discount is 134 / 100 X 25 = 33.50 and the sale price is $134 - $33.50 = 100.50
