How to Use Scientific Calculators

Today, scientific calculators are a mainstay for math students, science students, engineering fans and professional crunching computations every day. However, scientific calculators are not immediately easy to understand, and they do require a basic understanding of mid-level math, including algebra and trigonometry.



Instructions

• Remove the calculator from its protective case. Insert batteries into the back of the calculator and close the battery holder with its lid. Turn the calculator over and press the "On/Off" button. Look at the screen and wait for it to signal the calculator is ready
• Use the calculator buttons to punch in the desired formula for the calculator to compute. Look at the screen as the formula appears as desired. Press the "Enter" button to order the calculator to crunch the calculation
• Determine a variable formula to be computed. Type the formula into the calculator as it would be displayed if you wrote the formula on paper. Use the "x" and "y" symbols as necessary for unknown variables. Press the "Enter" button for the calculator to crunch the formula and solve for a specific variable. For graphical formulas, wait for the screen to display the related graph once calculated
• Use the "sin," "cos" and "tan" buttons to utilize trigonometry functions. Punch in the math formulas as you would write it on paper using the calculator buttons. Use the appropriate trigonometry button for the formula desired. Hit the enter button once the formula is complete. Let the calculator crunch the formula and look for the graphical display on the screen. Use the "C" or "Clear" button to wipe out the work for a new task
• Use the "Memory" buttons to save formulas that you plan to use frequently. Also read and consult the User's Manual for advanced features and troubleshooting when the calculator may glitch or not work as expected

How to Use Exponents on a Scientific Calculator

Exponents help express a number multiplied by itself a number of times in a shorter phrase. For example, instead of saying four times four times four times four times four, you could just say four to the fifth power. The number being multiplied by itself is called the base in the expression. The number of times that number is multiplied by itself is called the power in the expression. For example, given the expression four to the fifth power, four would be the base and five would be the power. Using a calculator can make computing the result much faster.



Instructions

• Enter the base of the expression you want to calculate. For example, if you wanted to compute five raised to the ninth power, you would enter "5"
• Pressed the exponent key on the calculate, usually "^" or "y^x," depending on your calculator
• Enter the power in your expression. Continuing the example, to compute five raised to the ninth power, you would enter "9"
• Press the enter or equals key to have the computer display the result. Finishing the example, after pressing the enter key you would see the result "1,953,125" displayed
