2.22.3.2 When making a package, how can I make a function that is already used by system?

https://mathematica.stackexchange.com/landing/r/digest?cta=question&id=224730

Obviously, Plus[a,b] is given by Mathematica but say I have a package and I want to name a function Plus[a,b]. How can I go about making a new function without overwriting the original function ...

2.22.3.3 Simplifying expressions using elementary properties of integrals

https://mathematica.stackexchange.com/landing/r/digest?cta=question&id=225023

I want to be able to use Simplify (or FullSimplify) to simplify expressions involving, for example, sums of integrals, for instance turning

\[ \int _a^b f(x)\,dx + \int _b^c f(x)\,dx \]
into
\[ \int _a^c\]
...
