This study aimed to identify the degree to which indicators of multiple intelligences are included in the advanced mathematics textbook for the eleventh and twelfth grades in the Sultanate of Oman. In this study, the researcher used the descriptive analytical method, and the researcher used the content analysis tool. It includes four intelligences: (logical intelligence, linguistic intelligence, spatial intelligence, and social intelligence). The researcher relied on paragraph analysis. The study found that the total frequency of linguistic intelligence was 528, that the highest frequency of linguistic intelligence values was in the eleventh grade, that the total frequency of logical intelligence indicators was 688, that the highest frequency was in the eleventh grade, and that the total frequency of spatial intelligence indicators was 688. 432 occurrences, the highest frequency was in the eleventh grade, the total frequency of social intelligence indicators reached 92 occurrences, and the highest frequency was in the twelfth grade. The study showed that there were statistically significant differences in the degree of inclusion of multiple intelligence indicators in the advanced mathematics textbooks for the eleventh and twelfth grades in the Sultanate of Oman due to the eleventh grade variable. The study recommended the importance of the mathematics book for the eleventh grade includes topics that take into account social intelligence, and the necessity of conducting future studies to evaluate the extent to which indicators of multiple intelligences are included in mathematics textbooks for other academic stages
