3. Input the elements of VctA: 1 = 2 =.
4. Perform the following key operation: 1 5 (VECTOR)2 (Data)
2(VctB)2(2).
• This will display the Vector Editor for input of the 2-dimensional vector
for VctB.
5. Input the elements of VctB: 3 = 4 =.
6. Press A to advance to the calculation screen, and perform the calculation
(VctA + VctB): 1 5 (VECTOR)3 (VctA)+ 1 5 (VECTOR)
4(VctB)=.
• This will display the VctAns screen with the calculation results.

Whenever the result of a calculation executed in the VECTOR Mode is a
vector, the VctAns screen will appear with the result. The result also will be
assigned to a variable named "VctAns".
The VctAns variable can be used in calculations as described below.
• To insert the VctAns variable into a calculation, perform the following key
operation: 15(VECTOR)6(VctAns).
• Pressing any one of the following keys while the VctAns screen is displayed
will switch automatically to the calculation screen: +, -, *, /. The
calculation screen will show the VctAns variable followed by the operator
for the key you pressed.
Assigning and Editing Vector Variable Data
Important: The following operations are not supported by the Vector Editor:
m, 1m(M–), 1t(STO). Pol, Rec, and multi-statements also cannot
be input with the Vector Editor.
To assign new data to a vector variable:
1. Press 15(VECTOR)1(Dim), and then, on the menu that appears,
select the vector variable to which you want to assign data.
2. On the next menu that appears, select dimension (
3. Use the Vector Editor that appears to input the elements of the vector.

15(VECTOR)1(Dim)3(VctC)1(3)
To edit the elements of a vector variable:
1. Press 15(VECTOR)2(Data), and then, on the menu that appears,
select the vector variable you want to edit.
2. Use the Vector Editor that appears to edit the elements of the vector.
• Move the cursor to the cell that contains the element you want to change,
input the new value, and then press =.
