Step 1: Break Down the Multiplication

Start by multiplying 756121 by each digit of 481, beginning from the rightmost digit (1) and moving left.

• Multiply by 1:
  ( 756121 \times 1 = 756121 )

• Multiply by 80 (8 shifted one place left):
  ( 756121 \times 80 = 60489680 )

• Multiply by 400 (4 shifted two places left):
  ( 756121 \times 400 = 302448400 )

Step 2: Align and Add the Results

Now, align the results based on the place value of the multiplier (1, 80, 400) and add them together.

Add these values:
( 756121 + 60489680 + 302448400 = 363394201 )

📌 Note: Always align numbers by their place value to avoid errors during addition.

Step 3: Verify Your Result

To ensure accuracy, use a calculator or estimation techniques. For instance, rounding 756121 to 760000 and 481 to 500 gives:
( 760000 \times 500 = 380000000 )
The actual result, 363394201, is close to this estimate, confirming its correctness.
