Algebra as Structure Math Example 1

Solution

1. 1
   Step 1: Addition: $a + b = b + a$ for all integers. Example: $3 + 5 = 5 + 3$.
2. 2
   Step 2: Multiplication: $a \times b = b \times a$ for all integers. Example: $3 \times 5 = 5 \times 3$.
3. 3
   Step 3: Both operations are commutative — same structural pattern, different operations.
