A problem of absolute value operators has been converted to a problem of operator matrices.With the properties of the Hadamard product,some inequalities have been obtained involving A*B+B*A,|A+B| and |A|,|B|.Absolute value of operator equation has been extended,and the more extensive version of the Bohr inequality obtained.
