Question

find the square of 2572 by using the diagonal method​

Answer 1

Answer:

Given number =256

Step 1: The given number contains two digits. So, draw a square and divide it into 4 sub squares as shown above. Write down the digit 6 and 7 vertically, as shown above.

Step 2: Multiply each digit on the left of the square with each digit on the top, one by one. Write the product in the corresponding subsequence.

If the product is two-digit, write the tens digit above the diagonal, and the units digit below the diagonal.

Step 3. Starting below the lowest diagonal, sum the digits diagonally.

If the sum is a two-digit number, underline the unit digit and carry over the lens digit to the next diagonal.

Step 4: underline all the digits in the sum above the topmost diagonal.

Step 5: the underlined digits give the required square number.

Hence, 256
