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!

This calculator is incapable of displaying simplified fractions (i.e. 1 ½), you will have to use the decimal value or contain your complex fraction in parenthesis. (i.e. (5/2).)

Given two fractions a over b and c over d, you can subtract the first from the second by entering

( c / d ) - ( a / b ) ENTER

The calculator will give you a decimal result, which you can (probably) convert back to a fraction by using the >Frac command. Press MATH 1 ENTER

( c / d ) - ( a / b ) ENTER

The calculator will give you a decimal result, which you can (probably) convert back to a fraction by using the >Frac command. Press MATH 1 ENTER

The >Frac command on the second page of the the MATH/Misc menu will display the current value as a fraction.

The calculator has two Input/Output modes, MthIO and LineIO. In MthIO the results are displayed as fractions or as radicals or a mixture of fractions and radicals. What it means, is that in MthIO the calculator does exact calculations. Radicals in denominators are gotten rid of by rationalization, fractions are reduced to the same denominators before addition or subtraction. Fractions are reduced to simplest form.

In LineIO all results are displayed as decimal numbers.

If a result is exact (fractions and radicals) it can be changed to decimal form by pressing the S To D key, the one above the DEL key.

MthIO is the default IO mode. To set it, press SHIFT MODE and select 1:MthIO. To set LineIO as the IO mode, press SHIFT MODE and select 2:LineIO

A fraction is just a number like (almost) any other. On most calculators, as you enter 6/5 the calculator displays its decimal value. When you press - the calculator waits for a number 2 then / then 5. Once you press the equal sign it will calculate 2/5 then subtracts it from the preceding result. The priority rules favor multiplication and division over addition and subtraction.

On some calculators you can keep a fraction in fraction format and operate on it with other fractions, and the result may be obtained as a fraction.

The gist of the story is that ON A CALCULATOR operations on fractions as performed like operations on any number.

Because the TI84 does supports fractions in a funny way. Tap (3/4+1/2) then tap MATH and tap ENTER twice and you get the answer 5/4.

The TI 89 has a MODE called exact/approximate. In the exact MODE it does fractions; 3/4 + 1/2 = 5/4. In the approximate MODE it does decimals; 3/4 + 1/2 = 1.25

Hello,

Use the [2nd][MATH] keys. Scroll right [F6] to the softmenu [->Frac or To Frac].

Hope it helps.

Enter the fraction for example: enter 8/12.

The answer will be .666666

Then click Math (which is located under the Alpha button).

Click the ->Frac button (the first one).

It should come up as Ans->Frac.

Click Enter.

It should now read 2/3 which is 8/12 reduced.

Note: I have a TI-84 Plus Silver Edition, and the TI-84 Plus might not have this function, but that is how I do it on my TI-84 Plus Silver Edition
