“I am very impressed with Geometry Expressions: dynamic construction and visualization combined with symbolic analysis, all in an easy-to-use graphical user interface. I believe this is precisely the type of intuitive computing that would be well-received by students and a real aid to their understanding of many mathematical topics. ”
“I was a secondary school teacher for 42 years and 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. It should be in every student's toolkit just as compasses and ruler have always been. ”
“The best thing about Geometry Expressions is the ease of use. GE has very convenient menus and one can do nice things like specify lengths of segments and have them appear as desired. ”
“Great product! I found it very helpful in visualizing different geometric forms and how they interact. I've been experimenting with gears, levers, cranks. ”
“I found Geometry Expressions very useful. It helped me solve in an easy way mathematical relations that are long and cumbersome to find by hand. It helped me concentrate on problems with a minimum waste of time for calculations. I think it will be very useful for teachers and for students interested in geometry. ”
“My students and I found Geometry Expressions very useful, and easy to use. The Geometry Civilized class enjoyed features that allowed them to make analytic representations of plane geometry theorems, and students in my Modern Geometry class also had fun checking out a variety of conjectures. Next time I teach Algebraic Geometry I will make sure that my students try to get access so they can get a feeling for the work we do in automated geometric theorem proving. ”
“You have done the greatest thing ever for geometry. Symbolic computation was the first hurdle, but symbolic geometry is a new world order! In five years, we will all wonder how we survived without you. ”
