Sir jha i aagya tha hm direct uske sth vala likh rhe the then 4I m direct 4 kyu nhi likha

[@mathskartfor12thclass24]

Yahan ham matrix me deal kar rahe then matrix form me likhte hain, I means identity matrix equivalent to 1. You can understand in this way 4= 4*1 = 4I. After writing in matix form we can only add, subtract, multiply kar sakte hain.
