Step 1. Make 3 columns and write the values of a², 2 x ax b and b² in these columns.

Step 2. Underline the unit digit of b² (in Column III) and add its tens digit, if any, with 2 x ax b (in Column II).

Step 3. Underline the unit digit in Column II and add the number formed by the tens and other digits, if any, with a² in Column I.

Step 4. Underline the number in Column I.

Step 5. Write the underlined digits at the bottom of each column to obtain the square of the given number. In this case, we have: 542 = 2916
