The natural textbook display is a way of displaying formulae in the closest possible way to handwriting. For example, fractions are displayed vertically. This makes it easy to write and edit formulae naturally without the complicated brackets. It is enabled by default on supporting calculators, including fx-82ES and fx-991ES. You can enable MathO mode using SHIFT SETUP, 1.

A Casio scientific calculator is a great tool for students and professionals alike. Its many features include basic arithmetic functions, trigonometric functions, and statistics. This calculator is also able to store up to 99 calculations, making it ideal for longer equations or series of calculations. Plus, the large display and keyboard make it easy to input and read information.
Scientific calculators are calculators designed to operate in multiple settings ranging from educational to professional. Their wide popularity among other simple digital calculators is because of the varied functions they perform. You can calculate your science, engineering, or other mathematical problems without a hitch on these devices.
Moreover, there are variations to scientific calculators like graphing and programmable. Graphing calculators support features like plotting graphs, solving simultaneous equations, and other tasks. Programmable calculators are more like general-purpose computers capable of performing the automatic sequence of operations.
Casio calculators are particularly famous among students, and if you own one, then find a Casio manual guide depending on your model. All manuals are available online, from Casio FX 991ES Plus to other Casio calculators.
As there are different steps involved in the process, knowing the kind of reset operation you want is essential to get the job done. A couple of steps are involved in resetting your scientific calculator to default.
Yes, you can get your scientific calculator back to normal/default settings. You can do so by following a key sequence that will erase all the memory stored on your scientific calculator and turn it back to its original form. If you own a Casio calculator, below are the key sequences that will open reset settings, and return your calculator to normal.
Resetting your TI-84 calculator will wipe all data and programs from the device and restore the original factory settings. Most professors and teachers will require you to reset your TI-84 prior to taking exams to prevent you from accessing saved formulas and information.
Whenever I use my calculator, and do an equation, for an example, 2+2. It would always give a decimal as the answer when clearly it is not. For 2+2, it says 4.0 instead of 4. For 9.2+1.2, it says 1.0 instead of 10.4. I really don't know what to do because I have finals coming up soon.
This mode allows you to quickly prepare your calculator for exams. This mode restricts access to memory, programs, functions and applications, so that these features would not be available during exams.
The Casio fx-82MS is a calculator with 240 functions, including basic and scientific functions. Its two-line display shows the calculation formula and the result at the same time. To get the most out of your Casio fx-82MS, take the time to get to know how it works, beginning with some basic functions.
Hold down SHIFT key and press reset button (on reverse - press pin into hole marked P). Press SHIFT to cycle through 5 display tests. Press REPLAY> key to enter keypad test (display flickers when a key is pressed). Use reset button to exit test.
WARNING: Invoking the test described below will result in the clearing of datamemory and mode settings. Further, this test requires partial disassembly of the calculator,which could result in permanent damage. See disclaimer.
The display self-test for the fx-65 is invoked by disassembling the calculator to locatethe "TEST" pad located in the lower left corner (when looking at the back of the calculator) of the circuit board. Use something conductive, such as the tip of a screwdriver, to momentarily short the contacts. Repeated shorting of the "TEST" pad willcycle the display through four test patterns. The first test pattern is all segmentsenergized, the second and third test patterns energize alternate segments, and the fourthtest pattern is a blank display. Press clear or ON on the front of the calculator toexit the self-test. Of course, reassemble the calculator.
Display Test. The display self-test for the fx-82TL is invoked by pressing and holdingthe SHIFT key, then pressing the reset button (labeled "P") located on the back of thecalculator. The SHIFT key is pressed to advance through the display test patterns. Thefirst test pattern energizes alternate rows of segments. The second test pattern is a blankdisplay, the third and fourth test patterns energize alternate segments, and the fifth testpattern energizes all segments. Continuing to press the SHIFT key will cycle throughthe second through fifth display patterns.
Keyboard Test. From any of the display test patterns, press the right-cursor key (Replayright key). However, it is recommended that the keyboard test only be invoked from the first orfifth test pattern. The display will shimmer while the key is held down (it appearsthat alternate rows of segments are being quickly energize and deenergized). You can then proceedto press any key, except the AC/ON, on the keyboard. The display will shimmer as long as akey is held down. Pressing the AC/ON key will exit the self-test and return the calculatorto normal operation.

The display self-test for the fx-270W is invoked by pressing and holding the OFF key,then pressing the reset button (labeled "P") located on the back of the calculator. TheAC/ON key is pressed to advance through the four display test patterns. The first test pattern is a blank display, the second and third test patterns energize alternate segments, and the fourth test pattern energizes all segments. The reset button on the back of the calculator must be pressed to exit the self-test.
WARNING: Invoking the test described below may result in the clearing of datamemory, program memory and mode settings. Further, invoking this test requires partial disassembly and possible modifications to the calculator, which could result in permanent damage. See disclaimer before dissassembly or modification.
The display self-test for the fx-6200G and fx-6300G is invoked by repeated closure of the "TEST" pad located on the back of the PCB of the calculator. See the Radio Shack EC-4033 self-test discussion for more details.
WARNING: Invoking the tests described below will result in the clearing of datamemory, program memory, and mode settings. Further, invoking this test using the alternativemethod for the fx-7400G, described below, requires partial disassembly and possible modifications to the calculator, which could result in permanent damage. See disclaimer before dissassembly or modification.
These two casio calculators have built-in internal, display, and keyboard tests.With the calculator off, the test mode is activated by pressing and holding the two keys highlighted in red on the illustration at the right, then pressing theAC/ON key. A menu of test options is presented.
Each test is activated by pressing the number for the appropriate test. For thedisplay test, press the EXE key (in blue on the illustration at the right) tostep through each display pattern until until the test option menu is again displayed. The keyboard test requires the pressing of each key in order, generallyfrom the upper-left, to the lower-right; the calculator prompts you to press theappropriate key. The RAM and ROM tests will display "- OK -" when the test finishessuccessfully; the EXE key must be pressed to return to the test option menu.
The self test is exited by selecting option zero. With the fx-7400G you must additionallyanswer "yes" (by pressing F1) to the "reset all memories?" prompt (the calculator will eventually lock-up if you answer "no," necessitating a hard reset using the reset button on the back of the calculator).
As an interesting note, the fx-7400G has a pair of pads on the circuit board which,when momentarily shorted, will also invoke the self-test mode. With the calculator facing down, and the battery cover removed, the self-test pads are the two D-shaped pads under the grey piece of tape to the left of the back-up battery. The switch above the words "BACK UP" must be pushed up to turn the calculator on before shortingthe pads. The switch must be pushed back down before the battery cover is replaced.
The fx-7400G PLUS has built-in internal, display, and keyboard tests. With the calculator off, the test mode is activated by pressing and holding the key in the upper-right cornerof the keyboard and a b/c key (the two keys highlighted in red on the illustration above), then pressing the AC/ON key. The "ZX942 TEST" page is displayed. Seven tests plus a reset option may be chosen.
The self test functions differ from the older fx-7400G in several subtle but significantways. First and most importantly, once the RAM test is completed, instead of returning tothe self test menu, self test is exited and RAM is cleared - avoiding the problem of the calculator locking up if RAM was not expressly cleared. Second, the ROM test displays more information about the test. Third, a "Cycle Test" has been added which cycles repeatedly through the display test until interrupted. 2b1af7f3a8
