Binomial Expansion Teaches how to choose the RIGHT partner (:

I always like to share with my students what each Math topic has to do with their everyday life, particularly their future.

Yesterday, I did Binomial Expansion. It's about finding the RIGHT partner (: It's about mastering the skills of finding the correct match based on a set of factors.

Just like this question, you see that there are 2 brackets. 1st bracket is good for now. 2nd bracket needs us to do some expansion work by using the FORMULAE (It's provided during GCE O Level Exams but some schools don't seem to provide it for their mid year, strange)
Oh yar, there is NO need to remember the Binomial Expansion Formulae!

Then one of the questions that often pop up is " When do we stop our expansion for [TEX](1+\frac {x}{3})^{12}[/TEX]?"

To answer this question, it depends on what type of partners you are looking for.

This is a topic some of which is learnt ever since Primary 6.

Through my years of coaching, I notice quite a handful of students form blocks when they dealt with this topic that starts with "A" and ends with "a".

Haha! Yes! It's Alegbra! I was introduced of this thing in Primary 6. It was the ONLY method my dad taught me to solve word problems then. I didn't understand what he was telling me.... totally huh? huh? huh?

Well, I am glad I figure out the x-es & y-es eventually. Many students tend to see algebra to be abstract. In fact, it can be explained in terms of apples, oranges, pears .... ( This is my ONLY drawing subject- basic fruits) Those who have the "good fortune" will know the level of drawing :-)
