Fakta menarik: Banyak buku teks matematika di Israel menghilangkan "kaki" bagian bawah simbol "+" sehingga tidak menyerupai tanda silang.
Simbol "+" diganti dengan huruf T terbalik.
"Can you imagine hating Christ so much, that you changed a symbol of mathematics?"
"Dapatkah Anda bayangkan membenci Kristus sedemikian rupa, sampai-sampai Anda mengubah simbol matematika?" posting akun X @Methodios007.
Grok (AI bikinan Elon Musk di X) juga memberi jawaban seperti itu:
Research shows many Israeli math textbooks, especially in religious schools, modify the plus sign to avoid resembling a cross, using an upside-down "T" (﬩) due to cultural and religious sensitivities. Secular schools may use the standard +, indicating variability.
Penelitian menunjukkan banyak buku teks matematika Israel, terutama di sekolah agama, memodifikasi tanda tambah agar tidak menyerupai tanda silang, menggunakan "T" (﬩) terbalik karena kepekaan budaya dan agama. Sekolah sekuler mungkin menggunakan tanda + standar, yang menunjukkan variabilitas.
