# Deleting Elements from Vectors

Since you've learned how to add elements to a vector, it's only natural to learn how to remove them as well. Everything builds up to this.

To remove an element from a vector, use the `-` sign before the index of the element you wish to remove. Remember, this action doesn't directly overwrite your vector, so reassignment is usually necessary. To remove multiple elements, you can provide a vector of indices after the `-` sign. For instance, to remove the third element from the `grades` vector, the operation would look like this:

Similarly, to eliminate the second and fourth elements from the initial `grades` vector, you would proceed as follows:

From the previous task, you have the `prices` vector with the prices of 6 items. Your task is:

1. Remove the `'Dining chair'` item from the `prices` vector. This item is the fourth in the vector. Save the changes by reassignment.
2. Display the modified `prices` vector.

1. Remove the `'Dining chair'` item from the `prices` vector. This item is the fourth in the vector. Save the changes by reassignment.
