I Add Five to Nine and Get to the Answer Is Correct but How

Have you ever come across the mathematical riddle where adding five to nine gives you the correct answer? It might sound confusing or even impossible at first, but let’s dive into the fascinating world of numbers and find out how this enigma can be solved.

The riddle itself seems paradoxical. How can adding five to nine result in the correct answer? After all, the sum of five and nine is fourteen, not the expected answer. However, the key lies in the way the riddle is phrased. Notice that it doesn’t ask for the sum of five and nine, but rather for the answer. This subtle distinction opens up a whole new realm of possibilities.

The answer to this riddle lies in the way numbers are represented. In our everyday decimal system, each digit has a place value, which determines its contribution to the overall value of the number. For example, in the number 59, the digit 5 represents fifty, while the digit 9 represents nine. By adding five to nine, we are not combining them as individual digits, but rather considering the sum of their place values.

To understand this concept better, let’s break it down step by step. When we add five to nine, we are essentially adding 5 units to 9 units. However, in the decimal system, once we reach ten units, we carry over to the next place value. So, when we add 5 and 9, we get 14 units. But in terms of place value, this is equivalent to four units in the ones place and one unit in the tens place.

Now, if we consider the riddle’s question again, it asks for the answer, not the sum. Therefore, the correct answer is the one that results from considering the place values. In this case, the answer would be 14, as it represents four units in the ones place and one unit in the tens place.

To further clarify this concept, let’s explore an example. Suppose the riddle asks you to add five to 79 and get to the answer. Following the same logic, we would first add 5 and 9, resulting in 14 units. However, this time we have to carry over the one unit to the next place value. Therefore, the correct answer would be 84, as it represents four units in the ones place and eight units in the tens place.

FAQs:

Q: Why does the riddle specify the answer and not the sum?

A: The riddle’s phrasing is intentionally misleading to test our understanding of place values and how numbers are represented.

Q: Can this concept be applied to numbers other than five and nine?

A: Yes, this concept can be applied to any numbers. It all depends on the place values and the specific digits being added.

Q: Is this riddle applicable to other number systems?

A: The riddle is specifically designed for the decimal system, where each digit has a place value. In other number systems, such as binary or hexadecimal, the rules might differ.

Q: How can this concept be useful in real-life situations?

A: Understanding place values and how numbers are represented is crucial in various fields, such as computer programming, engineering, and finance. It allows for efficient calculations and ensures accurate results.

In conclusion, the riddle of adding five to nine and getting to the answer might seem perplexing at first, but it can be solved by considering the place values of the numbers. By understanding how numbers are represented in our decimal system, we can decipher the correct answer. This riddle serves as a reminder of the importance of grasping the fundamentals of mathematics and how they apply to real-life situations.
