How to Use the Sharp EL-735 Financial Calculator

by Joshua DuvauchelleUpdated September 15, 2017

Years ago, people calculated business and financial equations using beans, pebbles and other rudimentary instruments. Today, you can use much more sophisticated equipment like Sharp’s EL-735 calculator. This hand-held device comes designed to help people quickly find the answer to common business and financial equations.

Basic Operational Instructions

Press the “ON” button, located on the top of the EL-735’s keypad. This powers on the device. Note that, if the calculator is already on, this button also serves as the “BREAK” key as indicated on its label. Breaking helps give preliminary results when you’re entering a long equation.

Switch the EL-735 to "Financial" mode instead of "Statistics" mode. Press the following buttons in succession: "2nd F" and "Stat." When in statistics mode, "STAT" flashes on the screen. When in financial mode, no designation appears on the screen.

Type in a number by pressing the corresponding keys that each represent the digits that you want. If you need to use a decimal point, press the button on the right-hand side of the keypad that's marked with a centered dot.

Switch the negative or positive nature of the number, if you need to, by hitting the "+/-" button. If switching to a negative number, the display will show the minus symbol. If the number is positive, no symbol will appear.

Correct any errors that you've accidentally entered into the EL-735. To delete a number--for example, if you typed 1.889 but really meant 1.887--hit the backspace key, designated on the keypad with an arrow pointing toward the right. If you want to delete the entire number displayed, hit the "C-CE" button.

Balance a Checkbook

Enter your existing checking account balance into the EL-735's memory. For the sake of this example, we'll use $907.93. Type "907.93" into the calculator's display, then press "X > M."

Subtract any withdrawals you've made from an ATM or at a store checkout counter. For the sake of this example, we'll use $40. Type "40" into the calculator, hit "+/-" to turn the "40" into "-40," then push "M+" to add this number to the stored balance in the calculator's memory.

Add any outstanding checks you may have that you've written from your account. For the sake of this example, we'll use checks totaling $26.22, $65 and $11.75. Enter "26.22" and press "M+," then repeat for the remaining checks.

Get your balance. Press "RM" to see the results of your calculations. If you’re using a paper register to track your money, enter the calculator’s results into the register.

Calculate Percentages

Type in the whole number out of which you're trying to calculate a percentage. For example, let's say you want to know what's 7 percent of 66. Type "66."

Press the "X" button.

Enter the percentage, in this case "7."

Push "2nd F" and "%." The result will display on the EL-735's screen.

Tips

To reset the EL-735, use the tip of a ballpoint pen and press the recessed reset button on the back of the EL-735. This deletes everything on the calculator, including any equations or numbers that you entered into its stored memory.
