I am having a hard time doing maths tutorial. It is just like caem in the past. Die, dying, died! I wonder how did I pass my caem in the past. It suddenly feel so miracle to me!!
Ok, university maths is tough. Right~ I should have known that when I am in poly, mugging for my caem and get 15/100 for my mid semester test. Opps! Haha!
I got so damn bored staring at university maths and I decided to go and look for PSLE maths to do! =x I heard that many parents are complaining about how difficult the paper is. There are many complains. I start wondering, why do parents ALWAYS complain about PSLE maths and not other subjects? It is always maths.
I remember there was a complain about this particular maths question for the 1988 kids.
What is the result for 1 + 2 + 3 + 4 + … … + 47 + 48 + 49 + 50?Many parents start complaining that it is too difficult for PSLE standard. So when come to my year being a primary 6 student, our teachers kept giving us tricky and challenging maths questions. These maths questions make us go gaga! LOL!
This year, it is the first year PSLE students can use calculator (hello! We only start using calculator in secondary school ok!). This year, the questions are tricky too. I heard that there are MANY! The most classic example they kept giving was.
Jim bought some chocolates and gave half of it to Ken. Ken bought some sweets and gave half of it to Jim. Jim ate 12 sweets and Ken ate 18 chocolates. The ratio of Jim's sweets to chocolates became 1 : 7 and the ratio of Ken's sweets to chocolates became 1:4. How many sweets did Ken buy?. Ans: 68 sweetsCan you solve the above question using models? Oh well, mathematics is getting harder every single year. One day, you will see the kids going around bald. I realise that mathematician or mathematics lectures are usually bald =x Maybe they think too much and kill too much brain cells.
One simple question before I end my post.
Curry puff shop sells puffs at $0.80 each. Offer:Buy 3 get 4th half price. If customer has $50, how many puffs can he buy if he buys as many as he can. Ans: 71 puffCrazy! Who will buy so many puff? Haha!
