Welcome to getting started with the BAII Plus

calculator. I’m Joshua Emmanuel. In this video

clip we’re going to learn how to set the BAII Plus calculator to our

preferred mode of arithmetic operations. The BAII Plus calculator uses two modes: The

Chain Mode & Algebraic Operating System

Mode By default the BAII Plus calculator is set to the

Chain Mode. To see this, press 2nd FORMAT press 2nd FORMAT Press the ↑ button The display shows Chn indicating that the calculator is operating in the

chain (chn) mode In this mode, the calculator solves the problem

in order that you enter the operators. For example, when you enter 5 + 4 × 2 The chain mode answer is 18, which obviously is incorrect. This is because the calculator first processes 5

+ 4, obtains 9 and multiplies the result by 2 to obtain 18. So in

the chain (Chn) mode the BAII Plus calculator solves the problem in

the order that you enter the operators. Lets us now look at the second mode called

AOS, Algebraic Operating System In this mode, the calculator solves the probblem

according to the heirarchy of arithmetic

operations like most scientific calculators do. That is, the calculator processes multiplication

and division operations before addition and

subtraction. To access ths mode, Press 2nd FORMAT Press the ↑ button, and Press 2nd SET. Now let us perfrom the

same operation we did earlier on in this mode. 5 + 4 × 2 and the result is 13. This is because the calculator followed the order

of operations and performed the multiplication

before addition. It first multiplies 4 by 2 to obtain 8 and then

adds five to the result. That was a quick overview of the two methods

the BAII Plus calculator uses. Thank you for watching

Excellent demonstration. Thank you for making this video, it was exactly what I needed and the instructions were very clear.

Thanks! very helpful

How do you get the calculator so that you can steer it with the mouse? How does that work, please?

Very helpful! Thank you

Thank you!

Thx

Casio calculator 1000% better than this one. Can't believe CFA exam uses this calculator. US math hugh…

Thanks very much. Very useful video

This whole playlist is incredibly useful, thank you, Joshua!
