How does it work? OpalCalc takes the concept of a PC calculator and one-ups it by allowing the user to insert natural language as part of the sum, along with multi-line support that allows users to go back and adjust previous calculations. It also implements on-the-fly calculation as users type, percentages, variable support, hundreds of units and functions and extensive notation support.OpalCalc Calculator

How do I use it in the classroom? Students can use OpalCalcin place of regular calculators, and especially in place of standard PC calculators. Because of its multi-functionality, OpalCalc is appropriate for math students of all ages.
