Question 1
What is the primary reason order of multiplication affects computational cost?
- Multiplication is not associative
- Different dimensions are involved
- The number of operations varies
- All of the above
💡 Hint: Think about how operations change based on grouping.
Question 2
True or False: The associative property guarantees the same number of operations regardless of multiplication order.
- True
- False
💡 Hint: Reflect on how we multiply matrices.

Challenge Problems
Push your limits with challenges.
Question 1
Given matrices of various dimensions, evaluate the computational cost of each multiplication order. Specifically, for matrices A(2x3), B(3x4), C(4x2), and D(2x5), determine which order minimizes the total operations.
💡 Hint: Countdown from each split and compare the sums.
Question 2
Create a recursive function that implements the cost calculation method for any given set of matrix dimensions.
💡 Hint: Use the structure we discussed in class to outline your function.
