469.368 + 76.438 + 5.679: A Step-by-Step Guide to Solving Basic Arithmetic Operations

In this article, we will delve into the world of basic arithmetic operations, specifically addition, and explore how to solve a simple problem step by step. We will use the example of adding three numbers: 469.368, 76.438, and 5.679. By breaking down the problem into manageable steps, we will demonstrate how to arrive at the correct solution.

Understanding the Problem

Before we begin, let's take a closer look at the problem at hand. We are tasked with adding three decimal numbers: 469.368, 76.438, and 5.679. To solve this problem, we will need to follow the order of operations, which dictates that we perform addition from left to right.

Step 1: Line Up the Numbers

The first step in solving this problem is to line up the numbers vertically, making sure that the decimal points are aligned. This will help us to perform the addition accurately.

Step 2: Add the Numbers

Now that the numbers are lined up, we can begin adding them together. We will start by adding the numbers in the hundredths place, then move on to the tenths place, and finally add the ones place.

Adding the Hundredths Place

In the hundredths place, we have 8 + 8 + 9. To add these numbers, we need to consider the place value of each digit. The 8 in the first number represents 0.08, the 8 in the second number represents 0.08, and the 9 in the third number represents 0.09. When we add these numbers together, we get 0.25.

Adding the Tenths Place

Next, we move on to the tenths place. We have 6 + 4 + 5. To add these numbers, we need to consider the place value of each digit. The 6 in the first number represents 0.6, the 4 in the second number represents 0.4, and the 5 in the third number represents 0.5. When we add these numbers together, we get 1.5.

Adding the Ones Place

Finally, we add the ones place. We have 9 + 7 + 5. To add these numbers, we need to consider the place value of each digit. The 9 in the first number represents 9, the 7 in the second number represents 7, and the 5 in the third number represents 5. When we add these numbers together, we get 21.

Adding the Decimal Places

Now that we have added the ones place, we need to add the decimal places. We have 0.25 + 1.5 + 0.21. To add these numbers, we need to consider the place value of each digit. The 0.25 represents 0.25, the 1.5 represents 1.5, and the 0.21 represents 0.21. When we add these numbers together, we get 2.01.

In conclusion, by following the order of operations and breaking down the problem into manageable steps, we were able to arrive at the correct solution. The final answer is 551.507.
