Hey there! Hello!
Not sure if you still need assistance, but I'd love to help out if you need it!
If I understand your question correctly, you're asking which addition property describes 0+25=25. If I'm correct in this assumption, this would be the Additive Identity Property. This property basically states that any number plus zero is going to equal the original number.
Some other addition properties includes the Associative Property (three or more numbers will equal the same thing no matter their order), the Commutative Property (two numbers added together will equal the same thing no matter their order), and the Distributive Property (the sum of two numbers multiplied by a third is equal to each number multiplied by the third number individually then added together).
Hope I provided some assistance, feel free to inquire further if you need any more clarification! :-)
