What is Calcudoku?

Calcudoku is an arithmetic puzzle on a grid where no digit repeats in any row or column. Cages outlined in bold must have their numbers satisfy a given target and operation. Calcudoku is the same puzzle as KenKen and Mathdoku — the name was popularised by the website Calcudoku.org and has since been widely adopted.
