**Inverse Process.** The inverse process is similar, the only difference being that it begins from the last place of the minuend, and the previously obtained partial differences are corrected, if required. The process is suitable for working on a *pâṭî* (board) where figures can be easily rubbed out and corrected. This process seems to have been in general use in India, and was considered to be simpler than the direct process.²
