so then can we call that C is a proper subset of A , as C is smaller than A??
And if no ? then what is the difference between proper/strict subset and subset ?
Also the symbol/sign of subset , the line drawn below , in other books and websites it's given that this symbol represents improper set . ? so what are the correct symbol for subset , proper set and improper set to be clear while anyone asks?(1 vote)
