Addition terminology: In an addition operation, the input operands are called the “augend” and the “addend,” whose sum produces the result.

Introduction / Context:
Clear language helps when documenting arithmetic units, verifying HDL, or teaching fundamentals. The standard names for the two inputs in addition are “augend” and “addend.”

Given Data / Assumptions:

• Binary or decimal does not change the operand naming.
• The operation is x + y = z.
• We consider integer addition here, but the terminology is general.

Concept / Approach:
The augend is the first operand; the addend is the second operand being added to the augend. Their order has no effect on the sum due to commutativity, but the names are widely used in arithmetic descriptions and adder block diagrams.

Step-by-Step Solution:

Verification / Alternative check:
Textbook diagrams typically label inputs to an adder as augend and addend, with carry chains for multi-bit adders.

Why Other Options Are Wrong:
Claiming dependence on floating-point or word length is incorrect; names are conceptual, not implementation-specific.

Common Pitfalls:
Using “operand A/B” instead is fine in engineering drawings, but knowing formal terms helps in academic contexts.

Final Answer:
Correct
