Is a programmable calculator that can be used to
perform calculations and operations manually or programmed to perform the same
calculations and operations as part of a program.
The TI-59 uses an algebraic operating system (AOS). With the exception of implied
multiplication using parentheses, such as (2) (3) = 6, calculations are entered
exactly as they are written. The AOS sorts operations as they are entered and
performs them in order according to an algebraic hierarchy. The hierarchy is as
listed in Table 7-1. For any given equation, some operations are performed
immediately, while others are held pending until hierarchy says they should be
performed.
