You are bidding on a 1888 Robinson's mathematical series book! This math book was used in 1890 as dated by the user inside the cover "louis hempler"! This is a rare find the cover is a bit worn but all the pages are t and not written on the pages inside the cover are and the back pages have some math work done on them but the actual instruction pages are free of any writing! They alway told us not to write in our text books only this was 100 years later! It is very interesting to read this education has changed so much over the years! this is a very neat old book! Please email me for more pictures or questions! Thank you for looking at my auction!! Save on shipping with multiple purchases!!!
