# Delete

 Deletedeletes the element at position n in expr. If n is negative, the position is counted from the end. Deletedeletes the part at position . Deletedeletes 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:
