#### Displaying x^1 as x^-1 and not as 1/x

```I was having hard time getting Mathematica to display x^-1 as x^-1 and
not as 1/x. So I tried Maple 14, and it also does the same.

So I thought I ask the maple experts here if there is a way to do this
in Maple. This was my orginal question, I am posting it here for the
Maple group.

When I type

x^-1

Maple replies

1/x

Is there a way to tell Maple to *display* terms with negative powers as
x^-n  and not as 1/x^n ? (i.e keep the term just like it would appear
on paper).

Another example, suppose I type

expr = a*x^-2 + b *x^-1 +

The reason I want to do this, is just for display purposes. When I print
the expression on the screen, I'd like it to look like x^-1 and not like
1/x (to better match how the expression look like in the textbook)

thanks

This topic was discussed here:

http://www.mapleprimes.com/questions/36803-Keeping-Negative-Powers?ref=3DFe=

One of the methods should work for you.

I wrote a Maple program to display SI units (and cal) like that in
order to keep track of my algebra in some physical chemistry. It also
always uses the same order: cal, m, kg, s, A or V or ohm, K, mol.
Neater methods may well exist! As it's over 100 lines I shall email it

There are many things that you will have to consider, but here goes a start: MakeBoxes[Power[x_, y_?(NumberQ[#] && Negative[#] &)], TraditionalForm] := SuperscriptBox[MakeBoxes[x, TraditionalForm], MakeBoxes[y, TraditionalForm]] MakeBoxes[Times[c_, p : Power[x_, y_?(NumberQ[#] && Negative[#] &)]], TraditionalForm] := If[OrderedQ[{c, p}], RowBox[{MakeBoxes[c, TraditionalForm], MakeBoxes[p, TraditionalForm]}...

(x
I feel like a small child asking this, but how can I get Mathematica to say (x - 1) instead of (-1 + x), or to give me 4 (1 - q) instead of the doubly annoying -4 (-1 + q) ? In brief, given the choice, I prefer to look at subtraction rather than negation. The binary operator instead of the unary. I'm not asking Mathematica to read my mind about the way I want every possible expression to look, rather I am hoping to find out how to transform something I don't like into something I like, in a way that is guaranteed not to change the value of the expression.

NAT: 1-1 mapping from 192.168.x.x to 10.168.x.x ?
Hi, I have a machine on a 192.168.x.x network that I would like to configure in such a way that it believes to be in 10.168.x.x. In other words, if a packet comes in from, say, 192.168.3.4, I would like it to be mangled as it was coming from 10.168.3.4. In the same way, I would like outgoing packets for 10.168.x.x to be mapped to 192.168.x.x. I read the iptables manual and found out abount DNAT and SNAT, but it seems what they do at most is mangle addresses into a pool of addresses, is a round robin fashion. I don't need round robin. I need a 1-1 mapping. Anybody knows if this is doab...

x==1 vs 1==x
--Apple-Mail-1--767860423 Content-Transfer-Encoding: 7bit Content-Type: text/plain; charset=US-ASCII; delsp=yes; format=flowed I'm against _premature_ optimization in theory, but believe that a certain innate knowledge of what is and what is not efficient is important for making reasonable choices in the first place. To that end, when I had to write code to handle exactly one case out of many, where I knew that the operator would be #==, I thought I'd test case versus if/elsif. As I expected, the case statement performed worse (thought not as much as I expected). On a w...

What is the difference between Java JRE 5.x and 6.x (1.5.x / 1.6.x) ???
What exactly is the difference between the JRE 5.x and 6.x (or 1.5.x and 1.6.x) versions of the Sun Java Runtime Engine for windows? Why does Sun maintain 2 different versions or streams or forks of the JRE? Is it true that version 5 was supposed to have an EOL this past October - or was it always EOL in October 2009?

Problem in "X (1).Re := X (1).Re + 1"
This is a thought experiment. First, in RM 4.1.6: * when the generalized_indexing is used within a primary where a name denoting a constant is permitted. This means declare package V is new Vectors (Complex); X : V.Vector; begin X (1).Re := X (1).Re + 1; end; is interpreted as declare package V is new Vectors (Complex); X : V.Vector; begin Reference (X, 1).Element.all.Re := Constant_Reference (X, 1).Element.all.Re + 1; end; Is this OK? If this is the truth, and if Vectors is implemented by reference-counting. (I don't know copy-on-write is permitted in Ada.Contain...
