Answer
Correct Answer: 2029272
Explanation
Given data
- Multiply 2056 by 987.
Concept / Approach
- Use 987 = 1000 − 13 to simplify.
Step-by-step calculation
2056 × 987 = 2056 × (1000 − 13)= 2,056,000 − (2056 × 13)2056 × 13 = 2056 × (10 + 3) = 20,560 + 6,168 = 26,728Therefore, product = 2,056,000 − 26,728 = 2,029,272
