@bemmesr@mathstodon.xyz yeah in that textbook there is no explicit rule that I was able to find. Lennes wrote a letter in some journal, IIRC, which clarified his position on this.
In some of his other textbooks it's made explicit, e.g. here https://archive.org/details/elementaryalgebr0000unse_l2r5/page/20/mode/2up

@FishFace@ioc.exchange I see, well he should have to answer to that if he really wants to hold on to the 150 year timespan. I may present this to him later if I fail to find such an example by someone other than Lennes.
