Multiplication by a scalar, and division by a scalar | HP 49g

Attempting to add or subtract vectors of different length produces an error message:

Multiplication by a scalar, and division by a scalar

Multiplication by a scalar or division by a scalar is straightforward:

Absolute value function

The absolute value function (ABS), when applied to a vector, produces the

magnitude of the vector. For example:, ,

, will show in the screen as follows:ABS([1,-2,6])ABS(A)
