TI-7 MathMate
The TI-7 MathMate is a basic educational calculator by Texas Instruments, designed for students in grades Kâ3. 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-12 Math Explorer is an educational calculator designed particularly for students in grades 3â5. The Math Explorer slotted above the TI-7 MathMate by offering fraction and exponent capabilities, as well as a pi button. The Math Explore .... The TI-7 MathMate was eventually replaced by the TI-10, which features a two-line display. References External linksMathMate by Texas Instruments - US and Canada {{microcompu-stub Texas ...

Calculator
An electronic calculator is typically a portable electronic device used to perform calculations, ranging from basic arithmetic to complex mathematics. The first solid-state electronic calculator was created in the early 1960s. Pocket-sized devices became available in the 1970s, especially after the Intel 4004, the first microprocessor, was developed by Intel for the Japanese calculator company Busicom. Modern electronic calculators vary from cheap, give-away, credit-card-sized models to sturdy desktop models with built-in printers. They became popular in the mid-1970s as the incorporation of integrated circuits reduced their size and cost. By the end of that decade, prices had dropped to the point where a basic calculator was affordable to most and they became common in schools. Computer operating systems as far back as early Unix have included interactive calculator programs such as dc and hoc, and interactive BASIC could be used to do calculations on most 1970s a ...

Texas Instruments
Texas Instruments Incorporated (TI) is an American technology company headquartered in Dallas, Texas, that designs and manufactures semiconductors and various integrated circuits, which it sells to electronics designers and manufacturers globally. 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 TI digital light processing technology and education technology products including calculators, microcontrollers, and multi-core processors. The company holds 45,000 patents worldwide as of 2016. Texas Instruments emerged in 1951 after a reorganization of Geophysical Service Incorporated, a company founded in 1930 that manufactured equipment for use in the seismic industry, as well as defense electronics. TI produced the world's first commercial silicon transistor in 1954, and the same year designed and manufa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Order Of Operations
In mathematics and computer programming, the order of operations (or operator precedence) is a collection of rules that reflect conventions about which procedures to perform first in order to evaluate a given mathematical expression. For example, in mathematics and most computer languages, multiplication is granted a higher precedence than addition, and it has been this way since the introduction of modern algebraic notation. Thus, the expression is interpreted to have the value , and not . When exponents were introduced in the 16th and 17th centuries, they were given precedence over both addition and multiplication, and could be placed only as a superscript to the right of their base. Thus and . These conventions exist to eliminate notational ambiguity, while allowing notation to be as brief as possible. Where it is desired to override the precedence conventions, or even simply to emphasize them, parentheses ( ) can be used. For example, forces addition to precede multipl ...

TI-108
The TI-108 is a basic handheld calculator manufactured by Texas Instruments aimed at introducing younger students to basic arithmetic and calculator functionality. The TI-108 is widely used among younger students due to its low cost, durability, and simplicity. Along with the more expensive and newer TI-10, this calculator targets the K-3 student group for whom it will likely be a first calculator. The TI-15 is targeted to older students. History The TI-108 is the last member of the TI calculator family to continue a design language first introduced in the mid-1980s, with textured keys and straight edges with curved bottom corners, as well as a recessed frame around the display. This design was also shared with the landscape-aspect Galaxy line of scientific calculators, though the textured keys were not used on contemporary portrait-aspect designs due to a lack of space. The current model 108 is, at least externally, virtually identical to the original TI-108 introduced in 199 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TI-12 Math Explorer
The TI-12 Math Explorer is an educational calculator designed particularly for students in grades 3â5. 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 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 recomme .... Texas Instruments calculators {{microcompu-stub ...
