Well, I was a Form 4 student when I wrote this. If there are any bugs, please forgive me.

In F4 Maths syllabus, Polynomial is one of the most important topics.
We have 3 key functions here.
1. Long division
- It is always a tiresome problem for students. Mistakes may be made as we need to write a lot of steps most of the time. Students can use this app to check whether their answers are true.
2. Factor generator / Factor searcher
- When doing Factor Theorem problems, students always use Trial and Error approach to look for factors. It is very inefficient. Now, we can use this app to list out all factor (in form ax + b) in a polynomial instantly.
3. Expansion
- It is also annoying when we multiply several polynomials together. This app can help you fix this with only one click! Amazing!
