Solve Basic Addition: Calculate 0 + 99

To solve this problem, we will apply the identity property of addition. This property states that adding zero to any number will result in the number itself. In mathematical terms, the identity property for addition is expressed as:

$a + 0 = a$

where $a$ represents any real number.

Now, we can apply this property to our specific problem:

• Step 1: Identify the two numbers involved in the operation: 0 and 99.
• Step 2: Apply the identity property: $99 + 0 = 99$.
• Step 3: Simplify the expression: $99$.

By applying the identity property of addition, we find that the expression $0 + 99$ is equal to 99.

Therefore, the correct answer to the problem is $99$.
