careful as not consistent with the image presented / ISBN

Except wanting commanding as the title suggests teaching MANDATORY AND SPECIALTY it receives that of SPECIFIC AND SPECIALTY. The ISBN is the SPECIALTY OF COMPULSORY and because if you look elsewhere tjrs is obtained that title and the ISBN, but ultimately it receives a book titled Maths SPECIFIC AND SPECIALTY with the ISBN of the book so what ???
While the book is no longer available and they sell us as a ghost, or there is an error in the title and statement must rely on the image ?????
Amazon thank you kindly correct something here because suddenly I find myself with a book that does not fit me.
