Cancel Mark \cancel

When to use Cancel Mark

Draws a diagonal cancellation line through an expression. In source, start from the exact \cancel command instead of imitating the rendered glyph with Unicode characters or manual spacing. This keeps the expression editable and gives the renderer enough structure to apply mathematical spacing correctly.

Syntax

\cancel

The documented syntax belongs to cancel. Keep every required argument, brace pair, and environment boundary intact when moving the command between an editor, Markdown processor, notebook, or publishing system.

Example

\cancel{x}+y

Rendered output

cancelled x

Copy and compatibility checks

• Copy \cancel exactly; changing its case or removing a leading backslash can turn it into plain text.
• Confirm that the destination loads cancel before relying on this command.
• Render the example once, then inspect grouping, limits, scripts, and spacing before publishing.
