The Objective of Peter Chew Theorem is to make it easier and faster to solve the problem of quadratic roots, by converting any value of the Quadratic Surds ¿¿into the sum or difference of two real numbers or the sum or difference of two complex number. Peter Chew theorem is AI age knowledge because the theorem can help convert all Quadratic Surds. In addition, the theorem can help convert easier and faster than current method. This will increase the effectiveness of mathematics teaching and learning. When the future epidemics such as Covid-19 occur in the future, it can effectively help mathematics teaching, especially for students studying at home. Presenting numbers in surd form is quite common in science and engineering especially where a calculator is either not allowed or unavailable, and the calculations to be undertaken involve irrational values. Therefore, the application of Peter Chew theorem in Engineering can make the teaching and learning of Engineering easier. Objectives Peter Chew Theorem is the same as Albert Einstein's famous quote : Everything should be made as simple as possible, but not simpler. In addition, Albert Einstein's also quote : i)If you can't explain it simply you don't understand it well enough, ii)We cannot solve our problems with the same thinking we used when we created them. iii) When the solution is simple, God is answering From the Albert Einstein's quote above, it can be seen that simplifying knowledge is very important.
