What is ViziSolve?

Vizisolve is the home website for the Visual RPN Calculator by math teacher and software engineer John Linstrum. The Visual RPN Calculator is a new generation RPN calculator which attempts to combine the best aspects of traditional RPN calculators and current generation algebraic calculators. It is a solo project by made freely available as is on the Microsoft App Store .

There is also an online version which is in work and which lacks some of the capabilities of the windows version (at least so far). It runs on recent versions of almost all browsers (but not Internet Explorer).

Current Features

Over time Visual RPN Calculator's feature set has been slowly building up to approach the calculators which cost lots of money at the store:

  • All the common scientific, trig, matrix and statistics functions
  • Extensive editing capabilities - change numbers in calculations, undo calculations and copy and move entries around on the stack
  • Lists - work with numbers combined into lists, making possible single calculations using multiple data points. This is a super powerful feature once you start using it.
  • Graphing - graph multiple equations at once, with highlight marks and pop-up labels for roots, graph intersects, and local minimums/maximums
  • Functional Programming using an unusual scheme that makes simple things easy and complex things possible.
  • Exact mode - for instance √8 = 2√2, 1/2 + 1/3 = 5/6, etc.
  • Ability to enter all the commands just using the keyboard (e.g. type sin, sqrt, etc. to execute those functions). Also, lots of keyboard shortcuts so if you're working on a PC you can keep your hands on the keyboard and not use the mouse at all if you want.
