• The result of this operation is stored in ListAns Memory.
Example
• You can specify the storage location in list memory for a calculation result produced by a list
calculation whose result is stored in ListAns memory. For example, specifying " ΔList 1 → List
2" will store the result of ΔList 1 in List 2.
• The number of cells in the new ΔList is one less than the number of cells in the original list.
• An error occurs if you execute ΔList for a list that has no data or only one data item.
3. Arithmetic Calculations Using Lists
You can perform arithmetic calculations using two lists or one list and a numeric value.

k Error Messages
• A calculation involving two lists performs the operation between corresponding cells.
Because of this, an error occurs if the two lists do not have the same number of values
(which means they have different "dimensions").
• An error occurs whenever an operation involving any two cells generates a mathematical
error.
