The right sequence of suboperations that are performed in arithmetic pipeline is –

A. Align the mantissas

B. Add or subtract the mantissas

C. Normalize the result

D. Compare the exponents

The correct order of floating-point arithmetic steps is —

• First, compare the exponents (D) to determine alignment.

• Then, align the mantissas (A) by shifting.

• Next, add or subtract the mantissas (B).

• Finally, normalize the result (C) to adjust exponent and mantissa.

Hence, the sequence is D → A → B → C.
