Press the [SHIFT][MODE] to access the (SETUP) screen. -See the screen capture below. Press [7:Sci] to select the output display format to be Scientific.

You will then be prompted to key in a number between 0 and 9 to choose the number of decimal digits.

If you do not want fractions nor radicals set the default Input/Output format to LineIO.

To do so press [SHIFT][MODE][2:LineIO]. After that perform the steps given above to select Scientific format for the output.

You want to change the display mode. Press SHIFT MODE. Then press 6 and a number specifying the number of digits after the decimal point for fixed decimal notation, or 6 and 1 or 2 to specify one of the floating point modes.

write as decimal over one as fraction.

multiply top and bottom for number of decimal places by 10^(number of decimal places) to eliminate decimal.

Find the greatest common factor (gcf) for both numerator and denominator and divide both by this number in this case 2.

Simplify result.

You convert the 6 to a fraction with the same denominator. 6 *10=60 Add the numerators. 60+9=69 giving the fractional notation of 69/10.

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].

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!

The error is in the eyes of the beholder. In scientific notation your value of 0.0095 is written as 9.5*10^(-3). Actually the calculator showed you more digits than you were asking for and its answer is more precise that yours. When you choose the Input/Output of the calculator to be LineIO, it will show the results as decimals. Howvever if the number to be displayed is too small or too large, the calculator will use the scientific notation.

To do exact calculations (whenever possible) set the Input/Output mode to MathIO. The result will be a fraction (19/1981). After that you can press the [S-D] button to convert that exact result to its decimal representation.

If you do not mind my advice, I suggest you learn how to interpret scientific notation, and familiarize yourself with the capabilities of this new type of calculators.

To configure the calculator for MathIO, press [SHIFT][MODE] to open the (SetUp), then select [1:MathIO]. In this mode, you will be able to see the expressions you type in as they would appear in a textbook:Fractions will appear as fractions, you will see radicals, etc. You can do a string of calculations in MathIO and convert only the last result to its decimal representation.

Yes, you would have to convert the fractions into decimal notation, represented as feet.

Example: 5' 3 1/2" is 5.29167'

By the way, the formula (that you know) is "plus", not "times" ....

a^2**plus** b^2 = c^2 (the square of the hypotenuse is the **SUM** of the squares of the two other sides)

Thanks for using FixYa!

Press SHIFT MATH 2 to switch to the LineIO mode. You won't see fractions then. However, if magnitude of the number is too large or too small, the calculator will switch to scientific notation in order to fit into the display.
