[Blindmath] Scientific calculator for high-school student

[Susan Osterhaus]

Hi Pawin,

Prior to the Orion TI-84+, we used the Audio Graphing Calculator (View Plus
Technologies) plus the Orion TI-36X (Orbit Research) talking scientific
calculator. The AGC was needed for graphing and matrices, while the TI-36X
was able to calculate most scientific computations (including all or most of
those you mentioned below). However, the Orion TI-36X DOES NOT GRAPH. The
Orion TI-84+ (APH and Orbit Research collaboration with TI) sold out of its
first batch immediately upon its debut and had 643 on back order a month
ago. My understanding is that those back orders will be arriving shortly.
So, apparently (from your APH communication) the next batch of back orders
won't be available until 2014.

Best wishes,
Susan

Subject: [Blindmath] Scientific calculator for high-school student

Hi, the members of Blindmath mailing list  I'm a visually impaired person
currently enrolled in the high-school curriculum emphasizing on scientific
and mathematic study in Thailand.
 Through my primary to middle school, we are not allowed to use any kind of
calculator in the examination room so I never own one.
 However, since the introduction of high-school curriculum, my instructor
told us that we are “required” to use the scientific calculator in the
examination room. Furthermore, from looking at the exercise sheets that my
instructor has given me, it is quite impossible to solve the questions by
hand (at least in the time given for the test); thus, the requirement above.
 This set me on a quest for a talking scientific calculator which led me to
find the Orion Ti-84+ talking calculator that fits all my needs.
 Unfortunately, my contact with APH this morning reviewed that the unit will
not be available until next year. (Which is way past my examination date.).
So, here is my question: is there any way that I can get this calculator
from other than APH?
 Or, is there any talking scientific calculator that is comparable to the
Orion?
My requirement right now is that it must do fraction and scientific
notation, can work with many levels of parenthesis, be able to calculate
trigonometric function, universal exponent and root, and solve real number 1
variable equation If anybody has any information or recommendation please
let me know.
Thanks in advance
P.S. sorry for my bad English.
P.S.2. Sorry if this is the duplicate; I didn't see my previous post on the
list.
Best regards
Pawin
