Texas Instruments BAII PLUS Tutorial To begin, look at the face of the calculator. Almost every key on the BAII PLUS has two functions: each key's primary function is noted on the key itself, while each key's secondary function is noted in white above the key. To use the function on the key, simply press the key. To access the white function above each key, first press the gray key with “2nd” printed on it, which we will call the "2nd shift" key, and then press the desired function key. (Note that the 2nd shift key is near the upper left corner of the calculator keyboard.) Turning the Calculator On and Off To turn on the calculator, press . To turn off the calculator, press . ON/OFF ON/OFF Note that the “ON/OFF” key is on the upper right corner of the keyboard. Also, we will designate keys throughout this tutorial by the use of small boxes, as above.

Also, note that pressing the 2nd shift key places a little “2nd” symbol in the upper left corner of the display. Press the 2nd shift key again and the symbol goes away. The key is a toggle key that switches back 2nd and forth between the “regular” and the “2nd” functions. is like the typewriter shift key. After you 2nd press , look only at the white writing above the keys. 2nd Note that the calculator has a continuous memory, so turning it off does not affect any data stored in the calculator, but it will erase any number showing on the screen.

Texas Instruments BAII PLUS Tutorial Page 2 Clearing the calculator is very important, since unwanted data in memory can result in improper calculations, and hence wrong answers. It is best to get into the habit of automatically clearing memory before starting a calculation.

Changing the Display To change decimals from 2 to 4, press . 0.0000 is 2nd FORMAT 4 ENTER 2nd QUIT displayed. To change from 4 places to 2, press . 0.00 is displayed. 2nd FORMAT 2 ENTER 2nd QUIT We usually set the display to 2 places, which is especially convenient when working with dollars and percentages. However, we often use 4 places when dealing with interest rates and rates of return that are entered as decimals.
