Will give brainliest xd select from the drop-down menu to correctly identify the property shown.

−7.9+(−9.03+(−0.1))=−7.9+(−0.1+(−9. 03))
is it associative property, commutative property, or opposite of a sum property?

The answer is "commutative property"

I try to explain, −7.9+(−9.03+(−0.1)) is the initial operation, that can be semplified in this way -7.9-9.03-0.1

−7.9+(−0.1+(−9.03)) is the operation commutated, simplifying it -7.9-0.1-9.03

It's the same, numbers are just switched of position.
