Hi, I'm Ai Ling Ong. I enjoy coaching students who have challenges with understanding and scoring in 'O' Level A-Maths and E-Maths. I develop Math strategies, sometimes ridiculous ideas to help students in understanding abstract concepts the fast and memorable way. I write this blog to share with you the stuff I teach in my class, the common mistakes my students made, the 'way' to think, analyze... If you have found this blog post useful, please share it with your friends. I will really appreciate it! :)
Very good video for students to learn Quadratic Equations, as well as a teaching tool for teachers and tutors. Keep sharing! I will share this video blogpost with my readers.
Thanks great mathematician for sharing knowledge. I am looking forward to learning more from you.
Many of us forget to change the inequality sign when we arrive at this stage
-12k < -36
k < 3
Glad you have shown a better way to avoid the above error.
Thanks
Much appreciated post. I find that even when I point out those mistakes, there's still a large percentage of students that make them.
