I don’t see how anyone could understand masechta eruvim without a good high school math background.
Several years ago, Prof. Yitzchak Levine, who writes a Jewish history column for the Jewish Press and is a university math professor, suggested that yeshivot reorganized their curricula so that the secular studies would be more integrated with the Torah study. For example, mathematics could be integrated with eruvim and biology with chullin. He got lots of support for the idea from frum academics like me, but no rosh yeshiva signed on.
