Microsoft Math 2007 New software helps students efficiently complete assignments while garnering the knowledge to succeed in the most difficult of school subjects. Today Microsoft releases Microsoft Math 3.0, a new software solution designed to help students complete their math and science homework more quickly and easily while teaching important fundamental concepts. Microsoft Math 3.0 features an extensive collection of capabilities to help students tackle complicated problems in pre-algebra, algebra, trigonometry, calculus, physics and chemistry, and puts them all in one convenient place on the home PC. Similar to a hired tutor, Microsoft Math 3.0 is designed to help deepen students’ overall understanding of these subjects by invoking a full-featured graphing calculator and step-by-step instructions on how to solve difficult problems.

Microsoft Math offers a variety of tools that address a wide range of tasks in math and science:
* A full-featured Graphing Calculator with extensive graphing and equation-solving capabilities expands students’ understanding of complex mathematics. * Using step-by-step math solutions, students are guided through problems in subjects ranging from pre-algebra to calculus, helping them solve equations more efficiently.
* The Formulas and Equations Library contains more than 100 common math equations and formulas that enable students to identify and easily apply the right equation to solve math and science problems.
* The Triangle Solver explores triangles and teaches students the relationship between different components used to calculate sides, angles and values and solve formulas.
* The Unit Conversion Tool allows students to quickly and easily convert units of measure, including length, area, volume, weight, temperature, pressure, energy, power, velocity and time.
* The new Ink Handwriting Support works with Tablet and Ultra-Mobile PCs, allowing students to write out a problem by hand and acquire assistance from Microsoft Math. Microsoft Math is scheduled to be available for download in early May 2007 for an estimated retail price of $19.95(U.S.).

Math Composer™
The Math Composer software is a powerful yet easy to use tool for creating all your math documents. It is a simple way for math teachers and instructors to create math worksheets, tests, quizzes, and exams. This math software is perfectly suited for use in a wide range of subjects including arithmetic, geometry, algebra, trigonometry, calculus, physics and chemistry.

Create any Diagram or Figure
Math Composer doesn't use pre-made graphics like "test bank" software. Everything is created within Math Composer and is fully editable. Math Composer is not just a drawing program either. All figures and diagrams are built using "snap-together" elements that adhere to certain rules. This keeps the construction process simple while still allowing you the freedom to create what ever you desire.

Edit Equations and Text
Math Composer contains a full-featured text and equation editor. Quickly write text and equations together without the need to switch back and forth between programs.

Create Grids and Graphs
Create any style of coordinate grid. Easily graph any equation just like on a graphing calculator.

Microsoft Math full-featured graphing calculator with 3-D technology helps students visualize and graph
math and science equations.

MATRIX is a matrix calculator program written to help linear algebra students. The program can be used to perform and check row reduction and other matrix operations.

Features:
MATRIX is a matrix calculator program written to help linear algebra students. The program can be used to perform and check row reduction and other matrix operations. After each operation, the page scrolls up and displays the result below the last result. As the page scrolls, a record of all of the computations is created which may be reviewed or printed. The pages may also be saved as files.

MATRIX uses rational arithmetic and displays all fractions as formatted fractions. There are no "round off " errors and the number of digits in numerators and denominators is unlimited.

The effort has been made to make this interface friendly. Little time or instruction is required to start computing with MATRIX.
