Mathpad

MathPad is a 100% free smart notepad that allows you to type in math expressions, assign variables, define functions, convert units, add units together and much more. There is no enter button, it automatically evaluates everything you type as you type it. And automatically updates anything dependent on a variable that has been changed or a function that has been redefined. The latest version is available in the links below.
