Understanding the Number Puzzle
The question presents a simple mathematical puzzle where a symbol '#' is used in place of a standard operator. We are given two examples of how this operator works and asked to find the result of a third expression using the same logic.
The given examples are:
- $5#3=8$
- $7#2=9$
We need to find the value of $9#4$.
Identifying the Pattern for '#'
Let's analyze the first example: $5#3=8$. We can see that if we add the two numbers, we get the result:
$5 + 3 = 8$
Now, let's check if this pattern holds for the second example: $7#2=9$.
$7 + 2 = 9$
The pattern is consistent. The operator '#' simply represents addition.
Applying the Pattern to Find 9#4
Now that we have identified the rule (the '#' symbol means addition), we can apply it to the expression $9#4$:
- Take the first number: $9$
- Take the second number: $4$
- Apply the identified operation (addition): $9 + 4$
- Calculate the sum: $9 + 4 = 13$
Therefore, the value of $9#4$ is 13.
Final Answer
Based on the pattern identified from the examples $5#3=8$ and $7#2=9$, the operator '#' represents addition. Applying this to $9#4$, we get $9 + 4$, which equals 13.
