Waise, ICSE's obsession with "AB exists but BA may not" is classic overcomplication—they'll have your child checking matrices for compatibility like I check milk for fat. CBSE Class 10 never asks you to actually *find* the inverse; they just want the formula, which is like selling a ghee tin without ever explaining the bilona process. My boy spent nights on ICSE matrix proofs while I was calculating GST on our jars—both feel equally puzzling, but only one puts food on the shelf.
