Introduction

Multiplication is a fundamental operation in mathematics that involves finding the product of two or more numbers. While calculators have made it easier to perform multiplication, there are times when we need to do it manually, such as when we don't have access to a calculator or when we want to practice our mental math skills. In this article, we will show you how to multiply 3504 and 164 without using a calculator.

Breaking Down the Numbers

To multiply two numbers without a calculator, we need to break them down into their individual digits and then multiply each digit by each other. Let's start by breaking down 3504 and 164 into their individual digits.

3504 = 3, 5, 0, 4
164 = 1, 6, 4

Multiplying Each Digit

Now that we have broken down the numbers into their individual digits, we can start multiplying each digit by each other. We will start by multiplying the digits of 3504 by the digits of 164.

Multiplying 3 by 1

When we multiply 3 by 1, we get 3.

Multiplying 3 by 6

When we multiply 3 by 6, we get 18.

Multiplying 3 by 4

When we multiply 3 by 4, we get 12.

Multiplying 5 by 1

When we multiply 5 by 1, we get 5.

Multiplying 5 by 6

When we multiply 5 by 6, we get 30.

Multiplying 5 by 4

When we multiply 5 by 4, we get 20.

Multiplying 0 by 1

When we multiply 0 by 1, we get 0.

Multiplying 0 by 6

When we multiply 0 by 6, we get 0.

Multiplying 0 by 4

When we multiply 0 by 4, we get 0.

Multiplying 4 by 1

When we multiply 4 by 1, we get 4.

Multiplying 4 by 6

When we multiply 4 by 6, we get 24.

Multiplying 4 by 4

When we multiply 4 by 4, we get 16.

Adding Up the Products

Now that we have multiplied each digit by each other, we need to add up the products. We will start by adding up the products of the digits in the ones place.

3 + 5 + 0 + 4 = 12
18 + 30 + 0 + 24 = 72
12 + 20 + 0 + 16 = 48

Multiplying the Tens Place

Now that we have added up the products of the digits in the ones place, we need to multiply the tens place by the product we got.

12 × 72 = 864
48 × 72 = 3456

Multiplying the Hundreds Place

Now that we have multiplied the tens place by the product we got, we need to multiply the hundreds place by the product we got.

864 × 100 = 86400
3456 × 100 = 345600

Adding Up the Products

Now that we have multiplied the hundreds place by the product we got, we need to add up the products.

86400 + 345600 = 432000

Conclusion

Multiplying 3504 and 164 without a calculator requires breaking down the numbers into their individual digits, multiplying each digit by each other, and then adding up the products. By following these steps, we can get the product of 3504 and 164 without using a calculator.
