Introduction

The column method is a popular technique used to multiply large numbers. It involves breaking down the numbers into their place values and then multiplying them using the standard multiplication algorithm. In this article, we will use the column method to multiply 75 and 1756.

Understanding the Column Method

The column method is a simple and efficient way to multiply large numbers. It involves breaking down the numbers into their place values and then multiplying them using the standard multiplication algorithm. The column method is particularly useful when multiplying numbers with multiple digits.

Breaking Down the Numbers

To use the column method, we need to break down the numbers into their place values. We can do this by writing the numbers in their expanded form.

75 = 70 + 5
1756 = 1700 + 50 + 6

Multiplying the Numbers

Now that we have broken down the numbers into their place values, we can multiply them using the standard multiplication algorithm.

Multiplying 75 and 1756

To multiply 75 and 1756, we need to multiply each digit of 75 by each digit of 1756 and then add up the results.

75 × 1700 = 127500
75 × 50 = 3750
75 × 6 = 450

Adding Up the Results

Now that we have multiplied each digit of 75 by each digit of 1756, we need to add up the results.

127500 + 3750 = 131250
131250 + 450 = 131700

Writing the Answer

The final answer is 131700.

Conclusion

In this article, we used the column method to multiply 75 and 1756. The column method is a simple and efficient way to multiply large numbers. It involves breaking down the numbers into their place values and then multiplying them using the standard multiplication algorithm. We can use the column method to multiply any two numbers, as long as we break them down into their place values and then multiply them using the standard multiplication algorithm.
