Hello!!! I forgot the usual mail on which I used to send inquiries!!!!! lol I have some questions. - If I have an open hand, how to make a difference between bending one finger among the five fingers, bending two fingers among the five, and finally bending the five fingers together? - what is the difference between "v", "v v", and "w"???? - what is also the difference between the above and when they are doubled one on the other????? - I also do not understand the difference between l+l and l*l !!!!!! Thank you for the answer!!!! In His blessings!!!!
