Tips & Tricks

Working with variables

You can store values using variable_name := value or the other way around value =: variable_name. All defined variables are available across pages within the same problem. This allows for building dynamic, interconnected content. Sliders, table columns and graph functions are stored automatically. To remove a variable, use the DelVar command. Alternatively, you can insert a new problem to clear all previous variables.

Using Problems

You can organize your document into separate Problems using Insert > Problem. Each Problem has its own set of variables, which are not shared across Problems. For example, function f can be defined differently in Problem 2 — a common scenario in school exercises.

Typing math expressions from the keyboard

If you’re fast at typing, you can enter mathematical expressions directly from the keyboard using syntax like sqrt(2), abs(x-5), or log(8,4). Inside a Math Box in the Notes app, press Ctrl M to convert typed input into formatted math. The same happens when the expression is evaluated. The image shows several examples with both formatted math and their corresponding typed input.

Special keyboard symbols in math expressions

In addition to math templates, many special symbols and functions can be entered directly from the keyboard. For example, @e gives the constant e and arcsin writes the inverse sine.
