Addition and subtraction

Four examples are shown below using the matrices stored above (ALG mode).

In RPN mode, try the following eight examples:

A22 `B22`+	A22 `B22`-
A23 `B23`+	A23 `B23`-
A32 `B32`+	A32 `B32`-
A33 `B33`+	A33 `B33`-

Multiplication

There are a number of multiplication operations that involve matrices. These are described next. The examples are shown in algebraic mode.

Multiplication by a scalar

Some examples of multiplication of a matrix by a scalar are shown below.
