BTW :the changes and advances made in Sage since the last edition of this book may warrant a revision, possibly a new edition. If only for the installation procedures (Conda installation, WSL on Windows, Github replacing Trac, etc...) and the interfaces (Jupyter replacing the Sage notebook, emacs as an alternative to command line, etc...).

Indeed, I found on page 43 the example: sage: 123 + \ ....: 345 468 which does not work presently. The first mention of "\" as an operator is on page 162, where it's given as a shorthand for solve_right in a table (with "/" as a shorthand of solve_left) It also occurs on p168 (sect. 8.2.2) [twice] , p281, p283 (with explanation), p302 (in a summary table). Even in the sections where it is used, `\` is used much more often as a line continuation . As far as the book is concerned, I think certainly fixing "\" to work as line continuation is definitely more important for its correctness, since that's used in much more places in the book (and also in all the chapters where `\` is used as an operator). In all the places except the summary table on p302, I saw the alternative solve_right spelling explicitly mentioned. So impact of deprecating the notation is rather limited.
