SOURCE: No decimal display on TI BA-II calculator

Your BA II PLUS stores numeric values internally to an accuracy of 13 digits. However, the numbers it displays depends on the number of decimal places to which you have it set (choice of 0–9 or floating decimal). To set the number of decimal places displayed to three: hit [2ND][FORMAT][3][ENTER]This setting also continues indefinitely (even though the calculator is turned off and on) until it is changed.

SOURCE: nPr and nCr key

Hello,

On calculators you calculate permutations and combinations as follows

Enter the number n then press key nPr, and the number r

1**8(nPr)5=1028160**

For combinations, use nCr key instead of nPr.

Hope it helps

SOURCE: Using e on the BA II plus financial calculator

Hello,

To use the exponential function, **you must enter the number then press [2nd][e to the x] or [e^x] for short.**

e^(-0.1) is entered as (-)0.1 [2nd][e^x], where **(-)** is the change sign key

You will need to use extra parentheses to avoid errors.**20 - 18*( (-)0.1 [2nd][e^x] ) [=]**

The Minus sign between 20 and 18 is the regular one. The** (-) **before the 0.1 is the change sign key **(-)** or sometimes labeled** +/-**. The asterisk is the multiplication sign.

Hope it helps.

SOURCE: is it possible to calculate cube root or higher

To extract the roots of orders higher than 2, you can use the universal power key labeled as [Y to x]. if the exponent is an integer 3, 4, 5, 6 etc.

it gives the cube the 4th power, 5th, 6th, etc.

If the exponent is 1/3, 1/4, 1/5, 1/6 you calculate the cubic root, the 4th root and so on.

When you use it to calculate the roots, the radicand (the number the root of which you are calculating) must be positive, otherwise you may get the result as a complex number.

The syntax of the command is value [Y to x] (1/ order of root)

Ex: cube root of 27 is entered as 27 [Y to x] (1/3)

SOURCE: Hi, are there MC, MR, M-, M+ functions in Texas

The calculator has 10 memories (0 to 9)

To store a number (13) in memory 6 type 13 [STO] 6

To erase the content of memory 6 (M6) store 0 in int: 0 [STO] 6

To recall the content of memory location M7 press [RCL]7

To operate on the content of memory location M5 the syntax is [STO] [Op] 5, where [Op] is the operation symbol [+], [-],[x], [/] [y^x]

Ex: to raise the content of memory location 4 to the power of the displayed value, you press [STO][Y^x] 4

To clear all 10 memory locations

press [2nd][MEM][2nd][CLR WORK]

In short, although you do not have the keys you are accustomed to, you have a lot more. And please do not blame me if you feel disappointed.

Make sure you use the +/- key (located just right of the decimal point key) to enter a negative number. For example, to raise 3 to the -2 power, press 3 y^x 2 +/- =

The same way you raise a number to a non-fractional power, using the y^x button. For your example, press

3 y^x ( 1 / 1 2 ) =

or

3 y^x 1 2 1/x =

3 y^x ( 1 / 1 2 ) =

or

3 y^x 1 2 1/x =

A histogram is a particular type of bar graph used to represent the distribution of a set of data. However, the BA II Plus** is not a graphing calculator, **so you will not be able to create a histogram on it.

The BA-II Plus is designed for financial applications. It does not do fractions, as do some calculators intended for school use.

Sorry if that wasn't the answer you wanted to see, but there it is.

25 = 23e^x

25/23 = e^x

ln 25/23 = x

Press 2 5 / 2 3 = LN

25/23 = e^x

ln 25/23 = x

Press 2 5 / 2 3 = LN

To raise a value to a power, use the y^x key located just above the 9 key. For example, to raise 2 to the third power, press 2 y^x 3 =

Unlike most calculators, there is no dedicated key for decimal exponents. You will have to use the above procedure to raise 10 to an exponent.

I gave up using the Texas BA II. I used an on-line mortgage calculator for interest only. I was able to get a full printout.

I would like to learn more about the BA II and how to do this type of math on it.

Thank you
