Geometry Expressions – innovative new teaching software links geometry and algebra

Saltire Software announces the launch of Geometry Expressions, the world’s first software to link geometry and algebra.

Educators and students describe Geometry Expressions as a dynamic new teaching tool for algebra and geometry.

Users create geometric models with an easy-to-use palette of drawing tools and a menu of algebraic and geometric constraints. Geometry Expressions then computes the algebra of the complete geometric model.

Geometry Expressions "allows the transition from using geometry skills to exploring the relationship between algebra and geometry," says Saltire founder Phil Todd.

"It reveals the algebra behind the geometry.

 "It's an ideal addition to teaching software in the math classroom – from beginning algebra to calculus and on up to advanced mathematics at college or university, as well as in geometry classes."

Viv Lawton, a teacher for 42 years in Australia says Geometry Expressions "should be in every student’s toolkit.

 "I would have loved to have had Geometry Expressions available as part of my teaching program. I think this is one of the great maths programs."

Prof Douglas Meade, University of Carolina, says, "I believe this is precisely the type of intuitive computing that would be well-received by students, a real aid to their understanding of many mathematical topics."

Users create geometric figures with a quick and easy palette of drawing tools. But instead of imposing numerical measurements on the sketches, Geometry Expressions uses algebraic symbolism to put constraints on the drawings.

Geometry Expressions’ powerful algebra engine then goes further to reveal the hidden algebra behind the geometry.

 "Geometry Expressions is about exploring geometry using algebra, and exploring algebra using geometry," says Phil Todd. "This is a tool for learning mathematics through exploration."

Notes to editors:

System requirements: Geometry Expressions is available for Windows 2000 or later. Linux and Macintosh versions will be available later in 2006. It requires a minimum of 256 MB RAM

Pricing: Geometry Expressions can be purchased from http://geometryexpressions.com at $495 for industrial and commercial users, $249 for teachers at all levels of education and $79 for students.
