Initial setup for Texas Instruments BA II Plus Professional

Also, this calculator displays two decimal places. Most of us want to use more, so if you want to change the number of decimal places, press 2nd à . à enter the number of digits you want it to display. Then press Enter, 2nd, and CPT to quit.

Tips for using Texas Instruments BA II Plus Professional in the CFA exam

Set Decimal Setting to “Floating”

In the initial setup, you know how to change the number of decimal places. But this tip is a little bit more than that. You can optimize your format features for the CFA exam. The setup is simple: 2nd à . à 9 à Enter. Of course, there are no nine places after the decimal, the maximum number of decimals that the calculator can display is actually eight.

However, nine is a floating decimal. It means that if you only need two places after the decimal on display, you will only get two places after the decimals. If you need seven, they will be there for you. This format makes the screen clearer because in the CFA program, sometimes you need a lot of accuracy after the decimal.

Change Chn to AOS

The Chn format demonstrates the chain order of operations. So whatever you type in your calculator, it will simply follow the order of the keystrokes that you have entered. For example, under Chn setting, 1 + 2 * 3 = 9.

However, with respect to the CFA exam, whether it is CFA level 1, CFA level 2 or CFA level 3, there are many calculations involving adding numbers in the numerator and dividing or using many exponents, especially when you use the discounting models. In other words, Chn is the least helpful format setting for the CFA program.

In other to reduce the need for brackets without affecting the accuracy of the result, using AOS is the ultimate tip you should now. The direction is pressing the down arrow four times à 2nd à Enter. AOS is Texas Instruments’ special Algebraic Operating System. And this system allows for the correct order of calculation.

Reset the calculator

What happens if you reset your calculator or replace the battery? During the exam, the proctors may pick up your calculator and reset it for you. We don’t know that that happens, but that’s the worst scenario, or maybe you inadvertently do it yourself.

So to reset the calculator to take it back to the mode when it’s straight out of the box, the direction is 2nd à Reset à Enter. Then, the calculator will ask if you want to reset by displaying “RST?”. If you hit the Enter button, you will end up resetting your calculator. To quit, press 2nd and CPT buttons respectively.

As you reset the calculator, the calculator will again display two places after the decimal. The calculator has reverted to the default. Thus, you then need to go back to the direction to set the decimal setting to floating and switch the Chn to the AOS.
