and their attempts to tame Complexity

Our patent pending methodologies, LIFT and CYCLE, insure that your business objectives will not be sacrificed to the whims or oversights of CAS architects and developers.

The most important question is how will a computer algebra system satisfy your prospects, make you money and serve your needs.
