Are you consistently losing points on Matrix Multiplication because of trying to multiply matrices of the wrong dimensions? If so, you're making the exact same error as 80% of your class.
Your Timeline
- Minute 1: Identify the variables. Don't start solving.
- Minute 2: Check for edge cases. Are you about to commit the sin of trying to multiply matrices of the wrong dimensions?
- Minute 3-5: Execute. Keep this application in mind: You can only multiply a 2x3 matrix by a 3x4 matrix. The inner dimensions MUST match. The resulting matrix will have the outer dimensions (2x4).
Stick to the timeline. Methodical execution beats panicked guessing every single time.
