Solve Addition Problem: 7 Blocks + 7 Blocks = Total Blocks

To solve this problem, we'll follow these steps:

• Step 1: Identify the given information and numbers to add.
• Step 2: Perform the addition accurately.
• Step 3: Match the calculated total with the given answer choices to confirm the correct answer.

Now, let's work through each step:
Step 1: The problem provides us with two sets of blocks, each containing 7 blocks. We need to find the total number of blocks after adding them together.
Step 2: Using the formula for addition, add the two sets of blocks: $7 + 7$. Performing this addition gives us:
$7 + 7 = 14$ Step 3: Compare this result with the given choices: the correct answer is indeed $14$, which matches choice $\text{id}=1$.

Therefore, the solution to the problem is $14$.
