Hi there

Can anyone explain the following calculation error? (The task seems quite simple.)
 

restart

Original - very unintuitive calculation error:

Vector(3, {(1) = 20.09230769, (2) = 32.43076923, (3) = 15.26153846}) = Vector[column](%id = 18446746432715486622)NULL

``

In 1D math it works:

Vector[column](3, [1306./65, 2108./65, 992./65]);

Vector(3, {(1) = 20.09230769, (2) = 32.43076923, (3) = 15.26153846})

(1)

````

Approximate works:

Vector(3, {(1) = 1306/65, (2) = 2108/65, (3) = 992/65})"(->)"Vector[column](%id = 18446746432750076862)

``

Multiplying by 1. works:

Vector(3, {(1) = 20.09230769, (2) = 32.43076923, (3) = 15.26153846}) = Vector[column](%id = 18446746432750171550)NULL

``

Hi there,

I'm new here. My first question:

Is there a way to make Maple output display explicit multiplcations signs in 2D-math?

Example:
When you enter 5*2^x Maple will output 5*2^x. Is there a way to make Maple display the multiplications signs in output in stead just implicit multiplication signs (i.e. whitepaces)? (I would settle for Maple display all multiplication signs in output - not just the ones which are made explicit in the input.)

I searched this site. No luck. I looked into "Typesetting Rule Assistant", but I couldn't find a way to alter the output of multiplication sign (*).

Can you guys help me?

Kind Regards,

Jens

 

P.S.: I'm a teacher from Denmark. We use Maple before college/university for a lot of pupils. Some less competent pupils have a tendency to overlook the whitespace.
