Calculingua is a web application for mathematical analysis and design. Therefore the dominant interface elements have been developed to allow rapid analysis. The major elements are:

  • Command Entry Bar -- Down there at the bottom. The Command Entry Bar is where you type your math commands.
  • Sidebar -- Over on the left. It shows various data items based on what you pick from the menu bar on the left. It defaults to a variable viewer that allows you to see what variables are in your workspace.
  • History Window -- That's were you're reading this. It's where you see the results of your math show up.
  • Top Bar -- Right above here. It has icons for things like modifying your account and logging out.


Calculingua is designed for math, so let's see how to do it:

  1. Let's say we want to add two numbers -- 2 and 5. To do that, type the following code in the the Command Entry Bar and hit enter:
    2 + 5
    You should see see that command be pushed to the History Window, followed by the answer. Note that without assigning this math to a variable, Calculingua assumes that you want the variable "ans" to equal this. Therefore, the variable "ans" now has the value 7.
  2. Okay, so what you really wanted was for the variable "my_variable" to equal 7. To achieve that, type the following and hit enter:
    my_variable = 5 + 2
  3. Then let's say you want to do something with your new viable... Type the following and hit enter to set "my_other_variable" to 716:
    my_other_variable = 100 * my_variable + (20 - 4)
  4. This is just the most basic example. Calculingua is really much more than a simple five function calculator -- it's designed to perform matrix mathematics. We'll not get into that here, but to learn about the rest of the functions of Calculingua, type the following followed by enter:
