Let's break down and solve each comparison, and then we'll generate the sequence of symbols based on the results:

Problem Breakdown:

1. a) -6 _ 6

   • $-6$ is smaller than $6$.
   • Answer: $<$

2. b) 0 _ -9

   • $0$ is greater than $-9$.
   • Answer: $>$

3. c) |7| _ -7

   • $|7| = 7$ (absolute value of 7 is 7) and $-7$ remains $-7$.
   • $7$ is greater than $-7$.
   • Answer: $>$

4. d) |−5| _ 3

   • $|-5| = 5$ (absolute value of $-5$ is 5).
   • $5$ is greater than $3$.
   • Answer: $>$

5. e) -10 _ |−9|

   • $|-9| = 9$ (absolute value of $-9$ is 9).
   • $-10$ is smaller than $9$.
   • Answer: $<$

6. f) |−1| _ 1

   • $|-1| = 1$ (absolute value of $-1$ is 1), and the other side is also $1$.
   • $1$ is equal to $1$.
   • Answer: $=$

Code (without spaces or commas):

$<,>,>,>,<,=$

Would you like more details on any specific comparison?

Here are 5 relative questions:

1. What is the absolute value and how does it affect numbers?
2. Why is $-6$ less than $6$?
3. How do negative numbers compare to positive numbers?
4. How does the absolute value change the sign of a negative number?
5. What situations use comparing numbers in real life?

Tip: When comparing numbers with absolute values, always convert them to positive first before comparing.
