When doing the sign for easy (if you are right handed) the right hand brushes up twice against the left hand fingers. The left hand doesn't move. Let me say that again,
the left hand is stationary. The only movement in the left hand is a
slight bending of the fingers as the right hand brushes upward against it.
Sample sentence: Do you think this class is easy?
If you do this sign with a single motion this sign will mean "almost."
