All about Long Multiplication
Long multiplication breaks a larger multiplication into place-value steps. You multiply each digit, carry any extra tens and then add the results in columns.
Knowing the method helps with large numbers that are too hard to multiply in your head.
Long multiplication lets you multiply big numbers by breaking the sum into steps. You multiply each digit of the bottom number by each digit of the top number, starting from the right. When a product is bigger than 9, you carry the extra tens to the next column.
Writing the numbers in columns keeps everything in its place. After all the partial products are worked out, you add them together to get the final answer. Taking your time with each step helps you avoid mistakes.
