# Delete

 Delete[expr, n]deletes the element at position n in expr. If n is negative, the position is counted from the end. Delete[expr, {i, j, ...}]deletes the part at position {i, j, ...}. Delete[expr, {{i1, j1, ...}, {i2, j2, ...}, ...}]deletes parts at several positions.
• Deleting the head of a particular element in an expression is equivalent to applying FlattenAt to the expression at that point.  »
• Deleting the head of a whole expression makes the head be Sequence.  »
• Deleting a whole expression gives the result Sequence[].
Delete the element at position 3:
Delete at position 2 from the end:
Delete at positions 1 and 3:
Delete in a 2D array:
Delete the element at position 3:
 Out[1]=

Delete at position 2 from the end:
 Out[1]=

Delete at positions 1 and 3:
 Out[1]=

Delete in a 2D array:
 Out[1]=
Delete in an expression with any head:
Delete at any position in any expression:
Delete a head to splice in its arguments:
Deleting the head of a whole expression gives a Sequence object:
