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: 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: 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)

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.

It is probably the flat wire. Try taking it apart and resetting the wire connections.

Hit "Fix" then the number of decimal places you want.

It's written in the back of the calculator, mate ! A TI BA ii Plus uses a CR2032 battery, which is 3V, 60 micro A.

Just go to the shop and give them the battery model.

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
