Place Value Addition: Adding 6 Tens and 7 Units to 12

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

• Step 1: Calculate the value of 6 tens.
• Step 2: Calculate the value of 7 units.
• Step 3: Add the values obtained in Steps 1 and 2.
• Step 4: Add this result to the initial number.

Let's work through each step:

Step 1: Calculate the value of 6 tens.
Each "ten" represents 10 units, so 6 tens equals $6 \times 10 = 60$.

Step 2: Calculate the value of 7 units.
Each "unit" represents 1, so 7 units equal $7 \times 1 = 7$.

Step 3: Add the values from Steps 1 and 2.
The total value of tens and units is $60 + 7 = 67$.

Step 4: Add this result to the initial number, 12.
So, $12 + 67 = 79$.

Therefore, when we add 6 tens and 7 units to the number 12, we obtain $79$.
