Show answer & explanation
Correct answer: B
The question asks to identify the term for the method of subtraction that uses an additive approach.
Step-by-Step Explanation
Understanding the Concept: The standard process of subtraction (A - B) can be mathematically transformed by adding the "complement" of the number being subtracted (the subtrahend) to the number from which you are subtracting (the minuend).
The Process: By finding the complement of the subtrahend, you convert the operation of subtraction into an operation of addition.
Terminology: Because this specific technique relies on number complements to function, it is formally referred to as complementary subtraction.
