Drop

FilledSmallSquare Drop[list, n] gives list with its first n elements dropped.
FilledSmallSquare Drop[list, -n] gives list with its last n elements dropped.
FilledSmallSquare Drop[list, n] gives list with its n element dropped.
FilledSmallSquare Drop[list, m, n] gives list with elements m through n dropped.
FilledSmallSquare Drop[list, m, n, s] gives list with elements m through n in steps of s dropped.
FilledSmallSquare Drop[list, , , ... ] gives a nested list in which elements specified by have been dropped at level i in list.

FilledSmallSquare Drop uses the standard sequence specification (see Section A.3.5).
FilledSmallSquare Examples: Drop[a,b,c,d,e, 2]LongRightArrow.
FilledSmallSquare Drop[a,b,c,d,e, -3]LongRightArrow.
FilledSmallSquare Drop[Range[7], 2, 5, 2]LongRightArrow.
FilledSmallSquare Drop can be used on an object with any head, not necessarily List.
FilledSmallSquare Drop[list, , ] effectively drops all elements except those in a submatrix of list.
FilledSmallSquare Example: Drop[a,b,c,d,e,f, 1, -1]LongRightArrow.
