Question 1

What is the primary purpose of dynamic programming in matrix multiplication?

  • To find the fastest algorithm
  • To minimize multiplication operations
  • To simplify matrix sizes

💡 Hint: Think about why we choose one method over another.

Question 2

True or False: The product of matrices is commutative, so the order of multiplication does not affect the result.

  • True
  • False

💡 Hint: Consider how the dimensions align.
