Worked Example

Step-by-Step

Let's find two numbers that add up to 16.

Step 1: Start with a number, say 8.
---Step 2: We need to find what number, when added to 8, gives us 16.
---Step 3: Think: 8 + ? = 16.
---Step 4: You can count up from 8 to 16 (9, 10, 11, 12, 13, 14, 15, 16). That's 8 more.
---Step 5: So, the missing number is 8.
---Answer: 8 + 8 = 16.
