Explanation Given Information: The provided expression 55 − 36 _ . Formula used: Steps to subtract whole numbers: Step 1: Round off the minuend and subtrahend to the first digit and then subtract them to estimate the difference. Step 2: Calculate the exact difference. Step 3: Now compare the obtained estimated difference with exact difference and identify whether the exact difference is reasonable. Step 4: Add the difference and subtrahend to check the exact difference. The minuend and sum should be equal. Calculation: Consider the provided numbers 55 − 36 _ . The minuend is 55 and subtrahend is 36
