From the developer:
DragNMath is a unique innovative calculator using a visual editor.
On a DragNMath document, formulas looks like in a formula editor but DragNMath goes further by doing the calculations !
To create expressions, you can use the built in functions (trigonometry, logarithm …) and also your own functions. You can create functions with as many arguments as needed. You can change the formula of a function while it is already used.
You may want to check out more software for Mac, such as Calculus, V-Planner or Metes and Bounds, which might be related to DragNMath.
