how to make VI like "+" ,"-" functions in Labview

[thingsful]

Is there any way to make vi the same as LabVIEW's own  functions, 
not only can not see the front panel ,but also can not see the back panel, like "+"or "-"  function in Labview.

I  have the same question

When creating a source distribution you can remove the front panel and block diagram in the source file settings:

Be aware that removing the block diagram prevents you from using the VI on a newer version of LabVIEW as it cannot be recompiled.

If you are looking to protect your IP you can apply a block diagram password.  Hackers have ways of defeating them but it will keep out the majority of developers from copying your code.

@LogMAN Thank you very much!  The program is ok, but the icon is missing.

Yes, I can see how that could be an issue. Unfortunately I'm not aware of a solution to fix the icon. The standard functions like Addition, Subtraction, etc... are not really VIs. They are written in C or whatever language they use to program LV nowadays. So, they can do stuff we can't.
