At Desmos, we imagine a world of universal math literacy, where no student thinks that math is too hard or too dull to pursue. We believe the key is learning by doing. When learning becomes a journey of exploration and discovery, anyone can understand – and enjoy! – math. To achieve this vision, we’ve started by building the next generation of the graphing calculator. Using our powerful and blazingly-fast math engine, the calculator can instantly plot any equation, from lines and parabolas up through derivatives and Fourier series. Data tables open up a world of curve-fitting and modeling. Sliders make it a breeze to demonstrate function transformations. As browser-based html5 technology, the graphing calculator works on any computer or tablet without requiring any downloads. It's intuitive, beautiful math. And best of all: it's completely free. Desmos is used by students, teachers, researchers, and general math enthusiasts from every state, and 169 countries.

Founded in 2004, Freudigman & Billings, LLC. is a boutique Educational Solutions firm dedicated to providing educational and learning solutions for elementary, middle and high school students. Our holistic approach to teaching standardized testing is based on a system developed by developmental educational psychologist Dr. Kimberly Freudigman, a former Yale research faculty member. Our group of carefully selected and trained tutors develops individualized programs for students based on their unique learning styles and seeks to teach students the necessary problem solving and information processing skills to improve test scores and increase overall student performance in school. In addition to providing test and homework coaching, we also work one-on-one with students who are experiencing difficulties in school based on a variety of developmental, psychological, behavioral and cognitive reasons.  Our process of ‘Educational Therapy’ involves diagnostic evaluation, interpretation of prior psycho-educational testing, development of specialized programs, and implementation of intervention strategies that are specifically targeted to the needs of the individual child.
