Calculate The Expression: $10.1 \times 80$

$$

Introduction

Mathematical Expressions are a fundamental concept in mathematics, and learning to calculate them is essential for problem-solving in various fields. In this article, we will focus on calculating the expression $10.1 \times 80$. This expression involves multiplying two decimal numbers, which can be a bit challenging for some students. However, with a step-by-step approach and a clear understanding of the concept, anyone can learn to calculate this expression with ease.

Understanding the Concept of Multiplication

Before we dive into the calculation, let's understand the concept of multiplication. Multiplication is a mathematical operation that involves adding a number a certain number of times. In other words, it is a shortcut for repeated addition. For example, $3 \times 4$ can be calculated as $3 + 3 + 3 + 3 = 12$. Similarly, $10.1 \times 80$ can be calculated as $10.1 + 10.1 + 10.1 + ...$ (80 times).

Calculating the Expression

Now that we have a clear understanding of the concept of multiplication, let's calculate the expression $10.1 \times 80$. To do this, we can use the following steps:

1. Multiply the numbers: Multiply $10.1$ by $80$.
2. Add the partial products: Add the partial products obtained in step 1.
3. Round the result: Round the result to the nearest hundredth.

Let's follow these steps to calculate the expression:

Step 1: Multiply the Numbers

To multiply $10.1$ by $80$, we can use the following formula:

$10.1 \times 80 = (10 \times 80) + (0.1 \times 80)$

Using this formula, we can calculate the partial products:

$(10 \times 80) = 800$ $(0.1 \times 80) = 8$

Step 2: Add the Partial Products

Now that we have the partial products, let's add them:

$800 + 8 = 808$

Step 3: Round the Result

Finally, let's round the result to the nearest hundredth:

$808.00$

Therefore, the result of the expression $10.1 \times 80$ is $808.00$.

Conclusion

Calculating the expression $10.1 \times 80$ may seem challenging at first, but with a step-by-step approach and a clear understanding of the concept of multiplication, anyone can learn to calculate it with ease. By following the steps outlined in this article, you can master the art of calculating mathematical expressions and solve problems with confidence.
