AOS™Algebraic Operating System
The AOS™Algebraic Operating System enablesyou to enter
numbers and combinedoperations into the calculatorina
straightforward sequence. To ensure yourcalculations are
performedin the correctorder, the AOS usesalgebraic rules
to assignpriorities to the mi
jatics operations.
Purpose
Pending
Operations
Withouta fixedsetof algebraic rules, a problem such as
16-8 ~2+6 mayhaveseveral possible answers,
depending ontheorderin which the operations are
completed. However, the Algebraic Operating System
solvesthis problem by completingthedivisionfirst
(8+ 2) and then completing the subtraction and addition.
Therefore, 16—-8=+2+6=18.
Ina problem such as 4 x5 = 20, simply entering 4 [k]5
does not produce the answer. The operation must be
completed by pressing an appropriate key suchas [=].
(Notethat multiplication can be completed by any
operation that has equal or lowerpriority in the
algebraic hierarchy.) Until completed, 45 creates a
pending operation.
The TI-95 can perform calculations containing a
maximumofeight pending operations.
Note: Immediate functions, such as x2, complete
themselves and do not need to be completed by pressing
anotherkey.
