Can you please be a little more specific how the keys misbehave? I. e. which keys did you press, what did you expect to happen, what happened instead? This isn't clear (at least to me, I'm not an X.org specialist) from the xmodmap lines. Thanks!

Hardware requirements:
Standard 104 keys keyboard with numeric pad. Any language.

How to reproduce:
Open Calc.
Write using just the numpad:
2*7/2.5
Will result in this "Malformed expression" instead:
2⋅7∕2,5

For console guys, try these commands using the numpad: "ls /", "ls *", "cd ..":
ls ∕
ls: no se puede acceder a ∕: No existe el archivo o el directorio
ls ⋅
ls: no se puede acceder a ⋅: No existe el archivo o el directorio
cd ,,
bash: cd: ,,: No existe el archivo o el directorio;

The keys that misbehave are:
Numeric keypad dash
Numeric keypad asterisk
Numeric keypad decimal

What did you expect to happen?
Numeric keypad dash should output a dash ("/")
Numeric keypad asterisk should output an asterisk ("*")
Numeric keypad decimal should output a decimal dot (".")

What happened instead?
Numeric keypad dash outputs a non standard dash ("∕")
Numeric keypad asterisk outputs an elevated dot ("⋅")
Numeric keypad decimal outputs a decimal comma (",")

Selecting "English (EEUU)" or "English (EEUU international with dead keys)" as layout does not solve this bug, so I must remove "Spanish" from the title.

summary: - Spanish numpad unusable on most applications
+ Numpad unusable on most applications

Found another one:
Numeric keypad minus
Numeric keypad minus should output a minus ("-")
Numeric keypad minus outputs a long minus ("−")

These keys used to work reliably on 12.04.4. I just "upgrade" to 14.04 thought:
sudo update-manager -d

Finally found a solution:
http://askubuntu.com/questions/598099/numpad-buttons-going-weird

dconf reset /org/gnome/desktop/input-sources/xkb-options

or

gsettings reset org.gnome.desktop.input-sources xkb-options

The problem was:
dconf read /org/gnome/desktop/input-sources/xkb-options
['keypad:future']
You can test the pain yourself with this command:
dconf write /org/gnome/desktop/input-sources/xkb-options "['keypad:future']"
And then try to use the calculator.
