8+11+21
=8+11+3
=22u have to add each section separately to a single digit, except 11 and 22 which never get further reduced, they remain 11 and 22 in all calculations as they are master numbers and have slightly different/additional qualities compared to their major groups 2 and 4 respectively
if u do not add in the above manner, there is a possibility of missing master numbers and for further calculations your compound number will be different
