    sir , according to me left identity exist , please correct me if i am wrong

    eduncle-logo-app

    sir, please reply

    eduncle-logo-app

    yes,you are correct.

    eduncle-logo-app

    since sum of these two elements is equal to 1 that's why the left identity doesn't belong to the original set.

    eduncle-logo-app

    yes , sum is 1 not zero , this implies left identity belongs to original set

    eduncle-logo-app

    Exactly.

    eduncle-logo-app

    eduncle-logo-app
