The TI-12 Math Explorer is an educational calculator designed for primary school students. The Math Explorer slotted above the TI-7 MathMate by offering fraction and exponent capabilities, as well as a pi button.
The Math Explorer has since been discontinued and was replaced by the two-line TI-15 Explorer.

Lisp machines are general-purpose computers designed to efficiently run Lisp as their main software and programming language, usually via hardware support. They are an example of a high-level language computer architecture. In a sense, they were the first commercial single-user workstations. Despite being modest in number Lisp machines commercially pioneered many now-commonplace technologies, including effective garbage collection, laser printing, windowing systems, computer mice, high-resolution bit-mapped raster graphics, computer graphic rendering, and networking innovations such as Chaosnet. Several firms built and sold Lisp machines in the 1980s: Symbolics, Lisp Machines Incorporated, Texas Instruments, and Xerox. The operating systems were written in Lisp Machine Lisp, Interlisp (Xerox), and later partly in Common Lisp.
Texas Instruments Incorporated (TI) is an American multinational semiconductor company headquartered in Dallas, Texas. It is one of the top 10 semiconductor companies worldwide based on sales volume. The company's focus is on developing analog chips and embedded processors, which account for more than 80% of its revenue. TI also produces digital light processing (DLP) technology and education technology products including calculators, microcontrollers, and multi-core processors.
In mathematics and computer programming, the order of operations is a collection of rules that reflect conventions about which operations to perform first in order to evaluate a given mathematical expression.
A graphing calculator is a handheld computer that is capable of plotting graphs, solving simultaneous equations, and performing other tasks with variables. Most popular graphing calculators are programmable calculators, allowing the user to create customized programs, typically for scientific, engineering or education applications. They have large screens that display several lines of text and calculations.
The TI-83 series is a series of graphing calculators manufactured by Texas Instruments.
The Speak & Spell line is a series of electronic hand-held child computers by Texas Instruments that consisted of a TMC0280 linear predictive coding speech synthesizer, a keyboard, and a receptor slot to receive one of a collection of ROM game library modules. The first Speak & Spell was introduced at the summer Consumer Electronics Show in June 1978, making it one of the earliest handheld electronic devices with a visual display to use interchangeable game cartridges. The company Basic Fun brought back the classic Speak & Spell in 2019 with some minor changes.
The TI-80 is a graphing calculator designed by Texas Instruments in 1995 to be used at a middle school level.
TI-BASIC is the official name of a BASIC-like language built into Texas Instruments' graphing calculators. TI-BASIC is a language family of three different and incompatible versions, released on different products:
The TI 73 series is a series of graphing calculators made by Texas Instruments, all of which have identical hardware.
TI-15 Explorer is a calculator designed by Texas Instruments, intended for use in classes from grades 3-5. It is the successor to the TI-12 Math Explorer. For younger students, TI recommends the use of the TI-108. For older students, TI recommends the use of the TI-73 Explorer.
The TI-30 is a scientific calculator manufactured by Texas Instruments, the first model of which was introduced in 1976. While the original TI-30 was discontinued in 1983 after several design revisions, TI maintains the TI-30 designation as a branding for its low and mid-range scientific calculators.
Derive was a computer algebra system, developed as a successor to muMATH by the Soft Warehouse in Honolulu, Hawaii, now owned by Texas Instruments. Derive was implemented in muLISP, also by Soft Warehouse. The first release was in 1988 for DOS. It was discontinued on June 29, 2007, in favor of the TI-Nspire CAS. The final version is Derive 6.1 for Windows.
V+ is a set-top box for Virgin Media's Virgin TV service, which provides personal video recording (PVR) and high definition (HD) functionality to customers who subscribe to the service. Virgin TV have taken a different approach from rival Sky's Sky+ and later Sky+ HD services, by implementing a rental scheme for the V+ Box. When Virgin TV was launched, there was an installation charge and a monthly charge for all customers with a discount for XL customers. On 1 June 2007 pricing was revised, with all customers paying a one-off set-up fee and TV M and L customers paid a monthly charge, while TV XL customers had no extra charges. Various deals to lower the set-up fee have been made available to all customers in order to compete with rival Sky.
The TI-Nspire is a graphing calculator line made by Texas Instruments, with the first version released on 25 September 2007. The calculators feature a non-QWERTY keyboard and a different key-by-key layout than Texas Instruments's previous flagship calculators such as the TI-89 series.
The TI-34 name is a branding used by Texas Instruments for its mid-range scientific calculators aimed at the educational market. The first TI-34 model was introduced in 1987 as a midpoint between the TI-30 series and the TI-35/TI-36 series. Earlier models included Boolean algebra features, though these were removed with the introduction of the TI-34II in 1999, which focuses more on fractional calculations and other subjects common in middle and high school math and science curricula.
The Texas Instruments Explorer is a family of Lisp machine computers. These computers were sold by Texas Instruments (TI) in the 1980s. The Explorer is based on a design from Lisp Machines Incorporated, which is based on the MIT Lisp machine. The Explorer was used to develop and deploy artificial intelligence software.
Titan Mare Explorer (TiME) is a proposed design for a lander for Saturn's moon Titan. TiME is a relatively low-cost, outer-planet mission designed to measure the organic constituents on Titan and would have performed the first nautical exploration of an extraterrestrial sea, analyze its nature and, possibly, observe its shoreline. As a Discovery-class mission it was designed to be cost-capped at US$425 million, not counting launch vehicle funding. It was proposed to NASA in 2009 by Proxemy Research as a scout-like pioneering mission, originally as part of NASA's Discovery Program. The TiME mission design reached the finalist stage during that Discovery mission selection, but was not selected, and despite attempts in the U.S. Senate failed to get earmark funding in 2013. A related Titan Submarine has also been proposed.
The TI-7 MathMate is a basic educational calculator by Texas Instruments, designed for students in grades K–3. The MathMate was unique in that it automatically performed order of operations. The MathMate slotted in between the TI-108 and the TI-12 Math Explorer.
The TI-32 Math Explorer Plus is a calculator by Texas Instruments specifically designed for middle school students. The Math Explorer Plus was offered as a more advanced version of the TI-12 Math Explorer. The TI-32 Math Explorer Plus offered trigonometric, exponential, logarithmic, and probability functions, and thus can be considered a true scientific calculator unlike the TI-12 Math Explorer.
Mango Plumo is an educational interactive video game collection developed by Canadian company Quebec Amerique and published by QA International, in collaboration with Quebec-based software commercialisation company Druide informatique. There are three titles in the series: Mango Plumo's Earth Adventure, Mango Plumo's Space Adventure, and Mango Plumo's Weather Adventure. The titles feature a bird named Mango who lives in a magical world. Mango must work to stop the plans of the evil sorcerer Hocus Pocus. The games are available in French, and were later translated to Italian and English.
