1. **State the problem:** Calculate the product of 15, 32, and 4. 2. **Formula used:** Multiplication of integers is associative and commutative, so we can multiply in any order: $$a \times b \times c = (a \times b) \times c = a \times (b \times c)$$ 3. **Calculate step-by-step:** - First multiply 15 and 32: $$15 \times 32 = 480$$ - Then multiply the result by 4: $$480 \times 4 = 1920$$ 4. **Final answer:** The product of 15, 32, and 4 is $$1920$$.
