Questions & Answers

Q: What is the first step in squaring a number using this technique?

The first step is to choose a base close to the number being squared, typically a power of 10 (e.g., 10, 100, 1000). Next, find the difference between the number and the chosen base.

Q: How do you make a partition in the process of squaring a number?

After finding the difference between the number and the base, make a partition on the left side. Write the sum of the number and the difference on the left side of the partition.

Q: Why is it important to write the correct number of digits on the right side?

The number of digits on the right side should match the number of zeros in the chosen base. If the base has one zero, only one digit should be written on the right side.

Q: Can this technique be used for larger numbers close to powers of 10?

Yes, this technique can be used for numbers close to powers of 10. By following the same steps of choosing a base, finding the difference, making a partition, and squaring the difference, you can find the square of larger numbers.
