zfit.core.operations.add(object1: Union[zfit.core.interfaces.ZfitParameter, zfit.core.interfaces.ZfitFunction, zfit.core.interfaces.ZfitPDF], object2: Union[zfit.core.interfaces.ZfitParameter, zfit.core.interfaces.ZfitFunction, zfit.core.interfaces.ZfitPDF]) → Union[zfit.core.interfaces.ZfitParameter, zfit.core.interfaces.ZfitFunction, zfit.core.interfaces.ZfitPDF][source]¶

Add two objects and return a new object (may depending on the old).

Parameters:	() (object2) – A ZfitParameter, ZfitFunc or ZfitPDF to add with object2 () – A ZfitParameter, ZfitFunc or ZfitPDF to add with object1

Multiply two objects and return a new object (may depending on the old).

Parameters:	() (object2) – A ZfitParameter, ZfitFunc or ZfitPDF to multiply with object2 () – A ZfitParameter, ZfitFunc or ZfitPDF to multiply with object1
Raises:	`TypeError` – if one of the objects is neither a ZfitFunc, ZfitPDF or convertable to a ZfitParameter
