What is 5482 × 5?

Explanation:
Multiplying by 5 is quickest when you use the fact that 5 × a number equals half of multiplying that number by 10. So for 5482, 5482 × 5 = (5482 × 10) / 2 = 54820 / 2 = 27410. You can also check by breaking it apart: 5482 = 5000 + 400 + 80 + 2, and 5 × each part gives 25000 + 2000 + 400 + 10 = 27410. That exact result is 27410; rounding or misplacing a part would lead to numbers like 27500 (if you rounded to 5500) or other close, but not the exact product.
