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!

Foods for Better Memory


One of the interesting questions I discuss with my students every year before major examinations is

‘What foods would you recommend for brain?’

Generally, I have heard about ‘berries’ and fish help in memory.

It wasn’t until recently that I came across an interesting article on Pickthebrain.com

Here’s a summary of the foods recommended in the article:

  1. Herb: Rosemary
  2. Tea (Yes! The beverage)
  3. Fruits & Vegetables; colors for boosting memory are dark red, blue and green.
  4. Fish & Nuts
  5. Dessert: Honey

More details here: ‘5 Foods To Remember For Better Memory‘.

So are there any specific foods you take to better your memory? I would love to hear from you! Leave me a comment.
