Reviewer on how to compute for determinant value of 4 x 4 Matrix.
Acquiring knowledge and skill on how to solve for determinant of 4 x 4 matrix is important in solving any four simultaneous linear equation. In the above example, determinant X1 ( detX1), detX2, detX3, detX4 and detX5 were computed. Then following Cramer's Rule, the solution for value of X1, X2 , X3, X4 and X5 can be calculated. Doing this calculation by hand is very time consuming but thanks to computer and internet advancement, it is now possible to solve this problem in less than a minute using your smartphone. Now our brain can be used for higher level of thinking such as scenario analyis and decision making.
INVBAT.COM mission is to create online tools so we can solve math problem in less than a minute using our smartphone.

Personal Augmented Intelligence (AI) Explanation
🧠 Augmented Intelligence vs Artificial Intelligence
Understanding the difference between collaboration and automation
🔍 Messaging Contrast
Augmented Intelligence is like a co-pilot: it accelerates problem-solving through trusted automation and decision-making, helping you recall, analyze, and decide — but it never flies solo.
Artificial Intelligence is more like an autopilot: designed to take over the controls entirely, often without asking.
💡 Why It Matters for IN-V-BAT-AI
IN-V-BAT-AI is a textbook example of Augmented Intelligence. It empowers learners with one-click recall, traceable results, and emotionally resonant memory tools. Our “Never Forget” promise isn't about replacing human memory — it's about enhancing it.
Note: This is not real data — it is synthetic data generated using Co-Pilot to compare and contrast IN-V-BAT-AI with leading EdTech platforms.
