Understanding the Trick

Let's break down the math trick for finding the squares of numbers from 1 to 100. The trick involves using the squares of numbers up to 25. Here's how it works:

1. Squares of Numbers from 1 to 25

To begin, it is essential to memorize the squares of numbers from 1 to 25. Although it might seem challenging initially, once you get the hang of it, the rest of the trick will become much easier.

2. Calculating the Square of 56

Let's take the example of 56. The first step is to consider 50 as 25. Then, calculate the difference between the number and 50:

56 - 50 6

The next step is to add this difference to 25:

25 6 31

The last two digits of the square of 56 will be the square of the difference:

6^2 36

Therefore, the square of 56 is:

3136

3. Calculating the Square of a Number Less Than 50

Let's consider another example, where the number is 43. To find the square of 43, we first calculate the difference from 50:

43 - 50 -7

Then, we square the difference:

(-7)^2 49

Finally, we add the difference to 25:

25 - 7 18

Therefore, the square of 43 is:

1849

Conclusion

Mastering math isn't just about memorization; it's about understanding the patterns and applying them effectively. The trick discussed above is one such effective method that can significantly speed up your calculations. With consistent practice and the help of resources like INSPECTOR CHALISA, you can master these skills and perform well in math.
