Associative Property of Multiplication
It is the additive property of equality, as the additive property of length, as applied to adjacent or parallel line segments.
I don't know what a 'mathematical' sentence is. I'd prefer to call it an English sentence that describes a mathematical process and makes a statement concerning mathematical matters.

The property illustrated by the statement "0 plus x equals x" is the additive identity property. This property states that the sum of any number and zero is the original number.
It is the property of commutativity.
It is the additive identity property of zero. For any value, a + 0 = a.
