From page 31 of the manual in English, available on HP's website at the link below:

**Number of Days Between Dates **

To calculate the number of days between two given dates:

1. Key in the earlier date and press [ENTER].

2. Key in the later date and press [g][?DYS].

The answer shown in the display is the actual number of days between the two dates, including leap days (the extra days occurring in leap years), if any. In addition, the hp 12c also calculates the number of days between the two dates on the basis of a 30-day month. This answer is held inside the calculator; to display it,

press [X><Y]. Pressing [X><Y]again will return the original answer to the display.

How to Use a TI-30XA

The TI-30XA is a scientific calculator with many functions. You can calculate problems with fractions and decimals, as well as solve problems of probability and functions. A scientific calculator computes the number sentence you type in using the order of operations: parentheses first, then roots and exponents, then division and multiplication and, finally, addition and subtraction.

Instructions

- How to Use a TI-30XA
- 1
Press the [ON/C] key to turn on the calculator. Press the [OFF] key to turn it off. To use the calculator in solar mode, put the solar panel in the light and then press the [ON/C] key. To turn it off when in solar mode, slide the calculator cover back on and it will automatically shut off.

- 2
Replace the batteries by first removing the cover and placing it face down. Use a Phillips-head screwdriver to unscrew the back panel. Remove the back panel and change the batteries. Screw the back panel back on. Press [OFF] [ON/C] and [ON/C].

- 1

Use the basic operation keys for addition [+], subtraction [-], multiplication [x] and division [/]. To change the signs of your values from positive to negative or vice versa, press the [+ -] key before the numbers you enter. Use the parentheses, [(] and [)], to command the calculator to solve what is inside the parentheses first. Press the [=] to solve the number sentence you entered into the calculator.

Find percents of a number by first typing in the number, then [x], then the percent number, [2nd], [%] and, finally, [=]. The [2nd] key allows you to use the commands that are written above each key. For example, to find 20% of 100, type in 100 [x] 20 [2nd] [%] [=] and the display will show the answer, 20.

Turn decimals into fractions by entering the decimal value, then pressing the [2nd] and [F D] keys, then [=]. Turn the fraction back into a decimal by pressing [2nd] and [F D] again. For example, to turn 0.5 into a fraction, type in 0.5 [2nd] [F D] [=].

Turn mixed numbers into improper fractions by entering the mixed number first. Type in the whole number, then the [a b/c] key, then the numerator, the [a b/c] key again and the denominator. Next, press [2nd] [d/c] [=], and the calculator will convert your mixed number into an improper fraction. Press [2nd] [d/c] again to turn it back into a mixed number. For example, to turn 1 1/2 into an improper fraction type in 1 [a b/c] 1 [a b/c] 2 [2nd] [d/c] [=], and the display will show the answer 3/2.

Switch the notation setting of the calculator between engineering, scientific and floating. To select scientific notation, press the [2nd] and [SCI] keys; this will display your answers in scientific notation as a number between 1 and 10 to a power of 10. Press [2nd] [ENG] to switch to the engineering setting; this setting displays values as a number with an exponent that is a multiple of 3. Press [2nd] [FLO] to switch to the floating setting. This is considered standard notation and will display the answer as a standard number.

Use the left arrow key to go back and delete numbers to the right of the cursor that you typed into the display. This must be done before you press [=]. To clear the screen, values and operations, press [ON/C] and [ON/C] again in battery mode, or [CE/C] and [CE/C] again in solar mode.

Hope it helps your problem. Thanks!

PRINT KEY:
To save paper you can only print what is displayed, even
in non-print mode.
Pressing after the entry of a number will print the entry
with the symbol “#” even in non-print mode.
Pressing will insert a separator into a number entry
such as a code, date, etc. Separators are displayed as a
period and dashes but printed as periods.
MEMORY + KEY / PRINT ON / OFF KEY:
Pressing selects print mode or non-print mode.
Cause the calculator to operate in a display / print or
display only mode, depending upon the calculator’s
present state.
“P” on the display: Print mode.
“NP” on the display: Non-print mode.
MEMORY – KEY / DECIMAL SELECTION KEY:
Pressing sets the number of decimal places in
the result.
“F” on the display:
The answer is displayed in the floating decimal system.
“3, 2, 1, 0” on the display:
Presets the number of decimal places in the answer.
“A” on the display (Add mode):
The decimal point in addition and subtraction entries is
automatically positioned to the 2nd digit from the lowest
digit of entry number. Use of the add mode permits
addition and subtraction of numbers without entry of
the decimal point. Use of , and will
automatically override the add mode and decimally
correct answers will be printed.

Hello,

There are several ways you can extract decimal numbers from this fine calculator.

**In MathIO Mode**

1. Once a fraction or radical is displayed press [S<=>D] button to convert it to decimal. Pressing it again restores the fraction or radical display.

2. Instead of pressing the [=] key to obtain a result, press [SHIFT][=]. The result will be displayed as a decimal number.

**In LineIO**

If you do not care for exact calculations with radicals and fractions, just change the default mode from MathIO to LineIO. To do so

press [SHIFT]{MODE][2:LineIO]. In this input/output mode all results are decimal.

Please be informed that with this mode you will not be able to access the formula templates that allow you to enter fraction as you see them in textbooks (the natural display format). You lose other neat functionalities also.

As a suggestion, if you like the natural display for input keep it as default, and press [SHIFT][=] to display decimal results or [S<=>D] to convert display to decimal format.

Hope it helps.

Hi

if you put y= 3 or something like that; than your going to get a line try y1= 2x+3 for y1 and y2= -2x-3 press graph select zoomstd you should see two line form a x and some point if it does that that you calculator is okay . If all else check your manual and find the reset button this cure 99.99% all problems

Hello,

If you call a simple addition a problem it is no wonder that everything seems so difficult.

When you calculate the** sum **6.11 +6.11 , the calculator gives you a fraction reduced to it simplest terms, **611/50**. The result is correct, but it happens that you want it
expressed as a decimal rather than a fraction. To fix that all you have
to do is to press the button **[S<->D] ** above the red [DEL] key. It allows you to toggle the display format between fraction and decimal.

611/50 [S<->D] changes display to 12.22 and if you press the key again you go back to fraction

12.22 [S<->D] 611/50

Similarly, if you enter square root of 2 and it displays as a radical, you convert it to a decimal by pressing the key [S<->D].

The fraction and radical formats allow you to do exact claculations. But if you do not want to hear about that you can just press [SHIFT][MODE][2:LineIO] : Your calculator will do things the old way, but you will lose some important functionalities.

My suggestion is to set the default mode [MathIO] by pressing [SHIFT][MODE][MathIO] and to press the [S<->D] key to convert to decimal.

Hope it helps.
