Calculating the Scalar Multiplication of a Matrix
Your calculator supports the following types of scalar multiplication calculations.
n
× Mat A,
n
Mat A, Mat A ×
n
, Mat A ÷
n
• You can replace “Mat A” with any of the calculator’s matrices, from Mat A to Mat F, or
Mat Ans.
• For
n
, you can use a value, independent memory (M), variable, matrix name, constant (
π
or scientifi c constant), or scientifi c function value (like sin(30)).
Example:
2 0
0 2
+
1 2
3 4
×

This example assumes that Mat A contains
2 0
0 2
and Mat B contains
1 2
3 4
