Fill in the missing numbers to complete number bonds that equal 6.

Problem Overview:

The task involves filling in the missing numbers in a series of "number bonds" to 6. A number bond is a visual representation that shows how numbers can be split into parts. In this case, each bond consists of a total (6) and two parts that add up to the total.

Solution Approach:

For each bond, we need to determine the missing part such that the sum of the two parts equals 6. This can be done using simple subtraction:
- If one part is given, subtract it from 6 to find the other part.
- If both parts are missing, use logical reasoning or trial and error to ensure their sum is 6.
