Documenting Property Logic for System Formulas

A software developer is documenting a legacy billing formula represented by the expression 4y−9+94y - 9 + 9. To save on processing power, the developer wants to simplify this expression to 4y4y. Write a brief explanation for the technical documentation that identifies the specific mathematical property used to eliminate the constants −9-9 and 99. In your response, provide the name of the property, define what it states about the sum of opposites, and confirm the numerical result when −9-9 and 99 are added together.
