Introduction

The Enem (Exame Nacional do Ensino Médio) is a national high school exam in Brazil that assesses students' knowledge and skills in various subjects, including mathematics. One of the key areas of mathematics covered in the Enem exam is mathematical operations, which include addition, subtraction, multiplication, and division. In this article, we will focus on the addition operation and provide a step-by-step guide on how to solve a mathematical problem involving addition.

What is Addition?

Addition is a mathematical operation that involves combining two or more numbers to get a total or a sum. It is denoted by the plus sign (+) and is used to represent the total amount of something when two or more quantities are combined. For example, if you have 3 apples and your friend gives you 2 more apples, the total number of apples you have is 3 + 2 = 5.

How to Add Numbers

Adding numbers is a straightforward process that involves combining the numbers to get a total. Here are the steps to follow:

Identify the numbers to be added: The first step is to identify the numbers that need to be added. In the problem 3448 + 7302 + 495, the numbers to be added are 3448, 7302, and 495.
Line up the numbers: The next step is to line up the numbers to be added, making sure that the digits in the same place value (ones, tens, hundreds, etc.) are aligned.
Add the numbers: Starting from the rightmost digit, add the numbers in each place value. If the sum of the digits in a place value is greater than 9, carry the excess to the next place value.
Write the final answer: The final step is to write the final answer, which is the sum of the numbers.

Solving the Problem 3448 + 7302 + 495

Now that we have covered the basics of addition, let's solve the problem 3448 + 7302 + 495.

Step 1: Identify the numbers to be added

The numbers to be added are 3448, 7302, and 495.

Step 2: Line up the numbers

Here are the numbers lined up:

  3448
+ 7302
+  495

Step 3: Add the numbers

Starting from the rightmost digit, add the numbers in each place value.

  3448
+ 7302
+  495
------
  11745

Step 4: Write the final answer

The final answer is 11745.

Conclusion

In conclusion, addition is a fundamental mathematical operation that involves combining two or more numbers to get a total or a sum. By following the steps outlined in this article, you can solve mathematical problems involving addition, including the problem 3448 + 7302 + 495. Remember to identify the numbers to be added, line up the numbers, add the numbers, and write the final answer.

Frequently Asked Questions
