4. Frequently Asked Questions
Q: Why is 25 squared 625?
A: The essence of square operation is to multiply numbers by themselves. 25×25 is calculated vertically (5×5=25, 2×5=10 carry) and finally 625 is obtained.
Q: How to quickly calculate the square of other numbers?
A: You can refer to the following quick calculation formula:
- Numbers with units digit of 5: n5² = n×(n+1) then 25, such as 35²=3×4=12→1225
- Numbers close to ten: use (a±b)²=a²±2ab+b²
