SAT calculator program

From Wikipedia, the free encyclopedia

An SAT calculator program is a software application that resides on a calculator which is used in helping to answer Scholastic Aptitude Test (SAT) questions. The programs themselves are different from SAT preparation books and classes in that they are actually used during the SAT test, and contain programs to answer questions with common SAT math formulas or simply answer common SAT questions.

[edit] History

The first person known to create such a program was Greg Myers of Princeton, NJ. Myers saw the opportunity to create SAT calculator programs while noticing that many SAT review books simply give the reader many formulas to memorize. Myers and his brother, Doug, landed on the front page of the "Circuits" section of the New York Times.

[edit] Current state of SAT programs

While the programs began as a way to simply hard code formulas into the calculator, they quickly evolved into more than that. Today, SAT calculator programs can be used not only to solve many SAT problems which require common formulas, but also to solve problems such as simultaneous equations, or to check the answers of a variable simplification problem. In fact, the actual programs created by Myers can be found online, but there are also some similar programs which claim similar functionality. One such example is a software program titled "SAT_OS," which stands for SAT Operating System.

[edit] SAT Operating System

The SAT Operating System ("SAT_OS") is a software program (Operating System) designed for use on the Scholastic Aptitude Test (SAT), specifically, the Mathematics subsection. It was originally created with the intention of enabling one to rapidly calculate answers to most questions on the "New SAT" Math subsection. It was designed using the calculator-based programming language TI-BASIC. It is compatible with the TI-83+, TI-83+ Silver Edition, TI-84+ Silver Edition, TI-89, and TI-89 Titanium graphing calculators.

[edit] Description

The SAT Operating System was written and released into the public domain in March of 2005 by "Steve S" in time for the very first version of the "New SAT." The new SAT ushered in new types of mathematics problems, while others were discarded. "SAT_OS" incorporates almost all of the most recent mathematical equations, problems solving functions, and tools into a user-friendly Graphical User Interface (GUI). So far there have been two unique versions of the SAT Operating System: one for the TI-89/Titanium graphing calculators and one for the TI-83+/84+/Silver Edition(s) graphing calculators. One can download the TI-89 Version here. The TI-83+ Family version is available here. In addition, there is a visual installation guide located at this location.
