You definitely have done addition back in primary school.
So, let us now go through a few important arithmetic operations you have learnt.
Hopefully you have been working on more math 🙂
Today, I shall do a quick post on the Arithmetic System – the addition, subtraction, multiplication and division (also known as arithmetic operations) of numbers, in specific fractions and decimals first.

So, I guess there should be equal number of prime numbers and non-prime numbers in the world… right? That is if we go along the same argument as what the kid was saying.
However, are there negative prime numbers? Find out here.

So, we’re done with categorizing numbers. Now we need to represent them on a number line. How do we go about doing this?

Hahaha. 😀
So, we’ve seen the very special zero. What type of number is pi? There are actually other sets of numbers which we must know because all numbers are special in their own ways. Let’s take a look at them now! 🙂
Quote of the Week
Posted on: February 12, 2009
I’ve just watched The Curious Case of Benjamin Button yesterday, and I loved the movie.
One quote from the movie by Benjamin Button (played by Brad Pitt) that I really like, and I hope to share with you girls because this is what I hope for for each and every one of you:
For what it’s worth: it’s never too late or, in my case, too early to be whoever you want to be. There’s no time limit, stop whenever you want. You can change or stay the same, there are no rules to this thing. We can make the best or the worst of it. I hope you make the best of it. And I hope you see things that startle you. I hope you feel things you never felt before. I hope you meet people with a different point of view. I hope you live a life you’re proud of. If you find that you’re not, I hope you have the strength to start all over again.

Just for an introduction we shall look at one of the most interesting numbers in the world – zero.
Well, what would we do without zero? 🙂
Have you ever wondered how did zero come about and when it was discovered?

This article is about a horse who could supposedly do Math. Cool huh! 😀
Below is an excerpt from the full article found here:
Wilhelm Von Osten and Hans
In the late 1800s, a German high school mathematics instructor named Wilhelm Von Osten was pushing a few scientific envelopes from his home in Berlin. Among other things, he was a student of phrenology, the now discredited theory that one’s intelligence, character, and personality traits can be derived based of the shape of one’s head. But it was his keen interest in animal intelligence that would ultimately win him fame.
Von Osten firmly believed that humanity had greatly underestimated the reasoning skills and intelligence of animals. To test his hypothesis, he took it upon himself to tutor a cat, a horse, and a bear in the ways of mathematics. The cat was indifferent to his efforts, and the bear seemed outright hostile, but the arab stallion named Hans showed some real promise. With further tutelage, Hans the horse learned to use his hoof to tap out numbers written on a blackboard. Much to Von Osten’s delight, jotting a “3” on the blackboard would prompt a tap-tap-tap from his pupil, a feat which Hans could repeat for any number under ten.

Yes, girls. It’s like that when you reach secondary school – you find yourself having to handle like what, 2 times as many as the subjects you dealt with back in primary school, and homework increases by a tremendous percentage as well.
But what is percentage exactly?
