Hello,

Press [MODE] button, the [F3] (CAS) Put a check mark on the field Approx. Ok OK.

Even you do not do that modification you still can have numerical result in decimal form: Put a dot at the end of an integ numer. Thus 11./3 or 11/3. or 11./3. will give you 3.66666

Hope it helps.

How to solve 17-4z+2z=13


You are solving for "z". First, bracket the "z" values ad combine them to get this:

17 - (4z+2z) = 13.

This breaks down to:

17 - 6z = 13

Now, subtract 17 from both sides of the equation to get the "z" value isolated and the result is:

-6z = -4 (13-17= -4)

Since both sides are negative, you can drop the signs and get this:

6z = 4

To get the value of "z", divide both sides by 6 and the result is

z = 4/6

Simplify the fraction to z = 2/3.

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
  1. 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.

  • 4

    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.

  • 5

    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] [=].

  • 6

    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.

  • 7

    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.

  • 8

    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!

    2x^3+6x^2-x=3 I know -3 works for x. But so does -or+ square root of 2 divided by 2. I need the steps so I can see how you get -or+ square root of 2 divided by 2. The question says solve for x.


    On most calculators with a solver function, you can specify a starting value for the variable (in this case x) after pressing [Solve] but before pressing the = key.

    To get the three solutions, try entering the function, pressing [Solve] then an estimated starting point (say 0.5 or 0.7) then [=]. This should show the +root2/2 result (ie 0.7071067812).
    You should not need to enter the function again.
    Follow this by pressing [Solve] again, then another estimated starting point (say -0.5 or -0.7) then [=] to get the -root2/2 result.
    Similarly, then press [Solve] again, and enter another estimated starting point (say -2) then [=] to get the final solution of -3.

    On Casio calculators, the [Solve] function is usually found by pressing [Shift][Calc]. Note that the solver function generally won't return numbers in surd form, only as a decimal value.

    How do you determine absolute value on a TI30XA calculator?


    If you are looking for a key, there is none. However, you can still determine the absolute value easily.
    1. If you have a single number and its positive, the absolute value is the number itself.
    2. If you have a single number and it is negative, just drop the leading minus sign or negate it by pressing the change sign key (+ -).
    3. If you are handling a complicated expression just calculate it. When you obtain the final result (a number) use rule 1 or 2 above.

    How to use casio fx-9750G PLUS to find inverse???? (3*3)


    To calculate the reciprocal of a numerical value you can use
    1. 1 / numerical value or
    2. use the key sequence [SHIFT] [ ) ] (X to -1), if the number is already displayed (stored in answer Ans memory)
    Example: calculate the reciprocal of 13. Must be in Run Mode

    1 [/] 13 [EXE] result is 0.07692307692 or

    13 [EXE] to have 13 in Ans memory (displayed) and [SHIFT][ ) ] [X to -1] [EXE].

    For such a simple number as 13, calculating its reciprocal the second way seems ridiculous, but if the number is already displayed the second method is the only efficient one if you do not want to copy the result on a piece of paper and retype so as to calculate its reciprocal.

    How to use binomial in calculator


    The binomial probability distribution is defined as
    P(r;p;n) =(nCr)(p^r)*(1-p)^(n-r), where n is the number of trials, p the probability of success, and r the expected result.

    Let n=20, r=7, p=0.15 ( I do not know wether this exemple has any meaning in the context of your problem, but you have to enter values that mean something to you.) I am only showing you the key strokes

    To enter 20C7 you press 20 [SHIFT][nCr]7 ;
    To enter 0.15 to the power 7 you type 0.15[X to ] 7 the key is between
    [x²] and [log]

    To enter (1-0.15) to power 20-7, you type 0.85 [X to] 13
    With [*] standing for multiplication key , and [X to] the raise to power key, the exemple above can be entered as

    ( 20 [SHIFT][nCr] 7) [*] ( 0.15 [X to] 7 ) [*] ( 0.85 [X to] 13 ) [=]

    Here is a screen capture to show you what it looks like. However on this calculator the combination 20 [SHIFT][nCr] 7 is represented as nCr(20,7).

    How do I add and subtract on this thing?


    Hello,
    I do know what calculator you have but on most calculators you have digit keys to key in numbers, operation keys (multiplication, division, addition, subtraction), function keys (log, exponential, %, square root, square or a power) and you have the = key to obtain the result of the calculation.

    Press the [ON] button

    To add 2 numbers, exemple 12 and 13
    12 [+ key] 13 [= key]. Calculator displays 25, or 25.00 or 25.0000...

    To subtract
    13 [- key] 7 [=key] . Calculator displays 6 or 6.00, 6.0000....

    To multiply
    32 [x key] 5 [= key]. Calculator displays 160.

    You may have memory keys, to store values. They may be labeled M to enter a number in memory, M+ to add a number to the one already in memory, M- to subtract from the number already in memory.

    Hope it gets you started.
