Introduction

Multiplication is a fundamental operation in mathematics that involves the repeated addition of a number. In this article, we will focus on multiplying large numbers, specifically the multiplication of $143$ and $6$ . We will break down the problem into manageable steps and provide a clear explanation of each step.

Understanding the Problem

The problem requires us to multiply $143$ by $6$ . To approach this problem, we need to understand the concept of multiplication and how it can be represented as repeated addition.

Representing Multiplication as Repeated Addition

Multiplication can be represented as repeated addition. For example, the multiplication of $3$ and $4$ can be represented as:

3 \cdot 4 = 3 + 3 + 3 + 3 = 12

Similarly, the multiplication of $143$ and $6$ can be represented as:

143 \cdot 6 = 143 + 143 + 143 + 143 + 143 + 143

Breaking Down the Problem

To make the problem more manageable, we can break it down into smaller parts. We can start by multiplying $143$ by $1$ , then by $2$ , then by $3$ , and so on, until we reach $6$ .

Step 1: Multiplying 143 by 1

The first step is to multiply $143$ by $1$ . This is a simple multiplication problem that can be solved by multiplying $143$ by $1$ .

143 \cdot 1 = 143

Step 2: Multiplying 143 by 2

The next step is to multiply $143$ by $2$ . To do this, we can add $143$ to itself.

143 \cdot 2 = 143 + 143 = 286

Step 3: Multiplying 143 by 3

The next step is to multiply $143$ by $3$ . To do this, we can add $143$ to the result of the previous step.

143 \cdot 3 = 286 + 143 = 429

Step 4: Multiplying 143 by 4

The next step is to multiply $143$ by $4$ . To do this, we can add $143$ to the result of the previous step.

143 \cdot 4 = 429 + 143 = 572

Step 5: Multiplying 143 by 5

The next step is to multiply $143$ by $5$ . To do this, we can add $143$ to the result of the previous step.

143 \cdot 5 = 572 + 143 = 715

Step 6: Multiplying 143 by 6

The final step is to multiply $143$ by $6$ . To do this, we can add $143$ to the result of the previous step.

143 \cdot 6 = 715 + 143 = 858

Conclusion

In conclusion, the multiplication of $143$ and $6$ can be broken down into smaller parts and solved using repeated addition. By following the steps outlined above, we can arrive at the correct answer, which is $858$ .

Answer

The correct answer is:

D. 858
