Writing and Editing Math

Math in Corca is not plain text. Every symbol, number, and operator becomes part of a structured expression. That structure allows the editor to keep expressions consistent while you type, edit, copy, delete, or rearrange content. You can work with math the same way you work with text, but with additional safeguards and behaviors that preserve correctness.

Corca supports natural mathematical typing. You enter expressions the way you would write them on paper or a whiteboard. For example, typing x^2+3x+2 produces x2+3*x+2.

Corca converts your input into structured mathematics while you type. You can continue writing without interruption, and the expression remains editable at all times.

How natural typing in Corca works

You type what you need using standard mathematical notation. Corca recognizes patterns and builds the correct mathematical structure automatically. Suggestions appear while you type. You can accept a suggestion by pressing Enter or clicking the option.

You can also ignore suggestions and continue typing, then you'll get a plain text. Natural typing works consistently across simple and complex expressions.

Common typing patterns

The following examples illustrate typical input behavior.

These patterns apply consistently across expressions, including nested structures.

Nested expressions

Natural typing also works when expressions contain other expressions.

For example, typing sqrt(x^2+1)produces √(,x2+1).

Typing 1/(x+1) produces 1/(x+1).

You can keep building the expression step by step without switching modes.

Variables and symbols

You can create variables simply by typing their name and choosing the best option from suggestions.

Later, you can adjust details in the right panel, such as:

• symbol

• type

• name

• arguments

• indexes and labels

• color

This allows expressions to remain both readable and structured.

Editing after typing

Natural typing does not lock the expression. You can always:

• move the cursor inside the expression

• change numbers or variables

• add new terms

• delete parts of the structure

Corca updates the math automatically.
