Adding is a fundamental mathematical operation that is used to combine two or more numbers or quantities to find their sum. It is a basic building block for more complex mathematical operations and is an essential skill for solving problems in everyday life. In this article, we will define adding and provide five examples to help you understand how it works. We will also include a quiz at the end to test your knowledge.

Definition:

Adding is the process of combining two or more numbers or quantities to find their sum. When we add, we are finding the total of two or more values. For example, if we have the numbers 2 and 3, we can add them together to find their sum, which is 5.

In math, we use the plus sign (+) to represent the operation of adding. For example, the equation 2 + 3 = 5 shows us that we are adding the numbers 2 and 3 to find their sum, which is 5.

Examples:

1. Adding whole numbers:

Let’s say we want to find the sum of the numbers 4 and 5. We can represent this as an equation: 4 + 5 = 9. When we add these numbers together, we get a result of 9.

2. Adding decimals:

Now let’s say we want to add the numbers 0.6 and 0.7. We can represent this as an equation: 0.6 + 0.7 = 1.3. When we add these numbers together, we get a result of 1.3.

3. Adding fractions:

Let’s say we want to add the fractions 1/2 and 1/4. We can represent this as an equation: 1/2 + 1/4 = 3/4. When we add these fractions together, we get a result of 3/4.

4. Adding negative numbers:

Now let’s say we want to add the numbers -2 and -3. We can represent this as an equation: -2 + (-3) = -5. When we add these numbers together, we get a result of -5.

5. Adding mixed numbers:

Let’s say we want to add the mixed numbers 3 1/2 and 2 1/4. We can represent this as an equation: 3 1/2 + 2 1/4 = 5 3/4. When we add these mixed numbers together, we get a result of 5 3/4.
