Analysis:
The given expressions follow a certain pattern where the numbers are manipulated using symbols like '-' and '$'. We need to understand this pattern to find the value of 'A' in the expression 17-A$6=69.

Pattern in the given expressions:
- In the expression 11-2$10=70, we have 11-2=9 and 9*10=90. But the result given is 70, which is 20 less than 90.
- In the expression 1-6$4=16, we have 1-6=-5 and -5*4=-20. But the result given is 16, which is 4 more than -20.

Finding the pattern:
- From the above analysis, it is clear that the actual result is manipulated by adding or subtracting a fixed number after performing the main operation.
- In the first expression, 20 is subtracted from the actual result. In the second expression, 4 is added to the actual result.

Solving for 17-A$6=69:
- In the expression 17-A$6=69, we can apply the same pattern.
- Perform the main operation: 17-A=11
- Then, 11*6=66
- Since the result given is 69, 3 is added to 66 to get 69.
- Therefore, A=3.

Conclusion:
- By understanding the pattern in the given expressions, we can easily find the value of 'A' in the expression 17-A$6=69. It is essential to analyze the operations and the manipulation done to the results to arrive at the correct answer.
