Problem Analysis:
The task involves comparing numbers and expressions to determine whether one is greater than, less than, or equal to the other. The instructions provide a step-by-step approach to solving such problems:
1.
Evaluate any expressions: If one side of the comparison contains an expression (e.g., `7 + 6`), evaluate it first to simplify the comparison.
2.
Compare the simplified values: Once both sides are numbers, compare them using the symbols `<`, `>`, or `=`.
Given Problems:
#### Problem 1: \( 26 \quad \_\quad 31 \)
- Both sides are already numbers: \( 26 \) and \( 31 \).
- Compare the two numbers:
- \( 26 \) is less than \( 31 \).
- Therefore, the correct symbol is `<`.
#### Problem 2: \( 18 \quad \_\quad 13 + 6 \)
- One side is a number (\( 18 \)), and the other side is an expression (\( 13 + 6 \)).
- Evaluate the expression \( 13 + 6 \):
\[
13 + 6 = 19
\]
- Now compare \( 18 \) and \( 19 \):
- \( 18 \) is less than \( 19 \).
- Therefore, the correct symbol is `<`.
Final Answers:
1. \( 26 < 31 \)
2. \( 18 < 13 + 6 \)
Boxed Final Answer:
\[
\boxed{<, <}
\]
