BAII Plus Calculator – Normal and Scientific Modes

BAII Plus Calculator – Normal and Scientific Modes


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
