A-Maths Students' Wishlist: This Amazing Calculator


The school term has just started and it was exciting to meet familiar faces and new ones in our weekly tuition classes for both O-Level Maths, O-Level Chemistry and A-Level H2 Chemistry.

While I was teaching in my Secondary 3 Additional Mathematics class on the usage of their Scientific Calculator to solve linear simultaneous equations, one student pointed out there was a new calculator which is much more powerful in terms of functions. Another student in the O-Level class mentioned it too. I was excited about this new calculator!

I went searching for calculators in our centre and managed to find one in the cupboard! Casio fx-95ES Plus. It looks exactly like my current Casio model except it has additional functions like:

  • Displaying answers in surd forms! (Useful for Trigonometry, Surd!
  • Solving quadratic inequality! (Many students can't seem to get this right!)
  • Setting your base in logarithm! (You can forget about change base formula in logarithm!)

These are the new features that I observed, there could be more!

However, when I went to the Ministry of Education Approved Calculator List, Casio fx-95ES Plus wasn't in that list. Since this calculator was bought by my colleague Sean Chua from Popular bookstore last November, I was thinking maybe MOE has yet to update the list so I emailed them to confirm. And attached was their reply.

Lesson learnt:

  • Not all calculators sold in Popular bookstores are approved for usage in major examinations.
  • We must still learn our concepts well instead of relying only on calculator to help us!

Well, I'm going into the topic of Quadratic Inequality in a few weeks time, join me in my weekly O-Level A-Maths tuition classes before it's too late! Go to www.WinnersEducation.com NOW for the details!

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! :)

    I bought it in Popular bookstores Singapore but do note that it's not approved by MOE for exams usage.
