Understanding the Sum of Ten Concept
The Sum of Ten is a useful mental math strategy that helps simplify addition problems by breaking down numbers into manageable parts. Let's analyze the expression 19 + 7 + 4 using this concept.
Step 1: Break Down the Numbers
- Start with the first two numbers: 19 and 7.
- Notice that if we add 1 to 19, it becomes 20, which is a round number and easier to work with.
- So, we can think of 7 as 6 + 1. This allows us to add 1 to 19 first.
Step 2: Perform the Addition
- Add 1 to 19:
- 19 + 1 = 20
- Now, we have:
- 20 + 6 + 4
Step 3: Continue Adding
- Start with 20:
- 20 + 6 = 26
- Now add the last number:
- 26 + 4 = 30
Conclusion
Thus, the result of 19 + 7 + 4 is 30. Hence, the correct answer is option 'C' (30).
This method not only simplifies the addition but also enhances your mental math skills, making it easier to handle larger numbers in the future.

Break 4 into 1 + 3: 19 + 1 = 20 and 7 + 3 = 10. Then, 20 + 10 = 30.
