Math Net is a visual, graph-based calculator. Imagine a spreadsheet based on nodes in a network, not tables. Each node can hold values or an operator that works on its children. Unlike a spreadsheet, there are no cell references. Create a list using the "list" operator, comma separated values, or a unary operator with multiple children. Click the "Show Sample" button in the App Bar for an example. Click arrows on the nodes to grow the network. Click the output in each node to toggle the tooltip that shows the full output. This app is the precursor to the more intuitive and visually pleasing Vector Calc.More

Release 6 is $1.49. Release 5 is now free! I came up with a more intuitive way to display the nodes, especially when there are lots of lists and graphs. It looks different enough that I turned it into a new app called Vector Calc. In the future, I will be focusing my time on the development of Vector Calc. Release 4 fixes a bug so that scatter and line plots are not attempted when a list pair contains values that are infinity or are not numbers. Release 3 includes the ability to make a list pair that can be used for generating scatter plots, line plots, and calculating slope, intercept and r-squared values. Release 2 includes two new operations: sumofsq (sum of squares) and meanofsq (mean of squares).
