To understand how 6+6 and 6+8 are related, let's break it down step by step.

First, let's calculate 6+6. Start by adding the digits in the ones place, which are both 6. 6+6 equals 12. Since the sum is less than 20, we do not need to carry any numbers over to the next place value.

Now, let's calculate 6+8. Again, add the digits in the ones place, which are 6 and 8. 6+8 equals 14. As with the previous calculation, there is no need to carry any numbers over to the next place value.

So, in both cases, we have a sum of two numbers. However, 6+6 equals 12, and 6+8 equals 14. Therefore, the numbers 12 and 14 are related to the addition equations 6+6 and 6+8, respectively.
