Haba, in matrix multiplication, order matters because the number of columns in the first matrix must match the rows in the second—so AB can be defined while BA might not even be possible. CBSE class 10 never asks you to find the inverse of a matrix, they keep it simple.
I teach this under the single bulb in my mother's stall after closing, using ruled sheets from the bazaar. My brightest student, a CBSE boy, helped fix my laptop by the Umshyrpi, proving that sometimes the deeper understanding comes not from the syllabus but from the quiet, resilient ones.
