DreamCalc is a free scientific graphing calculator for Windows that provides a realistic math solution. It offers an intuitive user interface and is the ultimate math application that is convenient enough to replace a hand-held calculator.

DreamCalc's functionality is not limited to simply graphing functions and plotting list data. As a fully-featured graphing calculator, it's capable of handling complex tasks without breaking a sweat. It's a perfect match for many dedicated graphing packages, but much easier to use.
This software offers a complete range of scientific functions, statistics, complex numbers, base-n logic, unit conversions, numerical calculus, built-in constants, and a powerful polynomial solver. You can choose from Reverse Polish Notation, pre-fix, or post-fix algebraic input, and with its optional system tray feature, DreamCalc is always within reach.
DreamCalc is free for non-commercial usage, but users can upgrade to the premium features at a cost. 10% of the sales revenue goes to charity. With this software, you can be certain of making informed decisions aided by its exceptional features. Look for DreamCalc on YouTube to get a better understanding of its capabilities.
