M A T H

Don't you just LOVE math? I did too, until I was moved up into the top set because apparently, I'm smart enough to be up at the top. Of course, it doesn't matter that most of them are TWO FREAKING GRADES IN FRONT OF ME. 

TT_TT 

I'm really good at math, I know I am. Not trying to brag but... yeah... but I seem to be completey incapable of it these days. I've missed out on two homeworks and I have a third one to do and I don't get any of it!

How do you work out compound interest?

Smallest amount
Total amount          x 100 = BLAHBLAHBLAH?
 

^ ^ ^

WTF? >  < 

Really? On another note, you want me to work out SPEED, TIME AND DISTANCE? I wasn't there on Friday so I missed that lesson. I only had one lesson on it today, and it wasn't really to do much with that either. Limits of Accuracy.


I can prove that 4.9 recurring is 0.5

WHY WOULD I NEED TO KNOW THAT? WHYYYYYYY?

So let me confuse y'all unless you already know:


Let's say  x = 0.499999999etc

100 x = 49.9999999

10 x = 4.9999999

So, 90 x = 45. (100 x - 10 x)

90        1            
45  =    2    =  0.5


o.O When will I ever use that? 

Here, let me tell you a question from each homework sheet. 

PERCENTAGES (I had like two sheets on this DX)


For the following table find the percentage profit or loss.
Where necessary, round to 1 decimal place.


Sure...

Cost price, £ = 4.00.
Selling price, £ = 6.00.


Baring in mind we have to use that formulae that I stated above. 

Would it be 66.6 %?
Would it be  50%?
Would it be 33.3%?

WHICH ONE?! > _ < (My mum said 50 but I'm all like, 'I gives up. I hate math, it betrayed me.')


Second one: a sheep is bought for £40 and sold for £33. What is the percentage loss?

82.5%? WTF O.o
21.2%? ...
17.5%? ARGH.

I HATE PERCENTAGES.

Compound interest time >:( ((WHAT'S A SIMPLE INTEREST O.O?))


"A man borrows £2000 from a bank. The bank will charge him 13% interest every year. He needs money for 6 years. The bank don't ((LOL she made an error)) tell him if they will charge him simple interest or compound interest. 

a.) work out, using simple interest, how much he will owe the bank at the end of the time period.
b.) work out, using compound interest, how much he will owe the bank at the end of the time period."


What. the. absolute. FUDGE?

2000 x (1.013)6 = 2161.158741.

But obviously it's money so...

2161.16, right?

Does anyone here actually get it? :'(

AND STD'S! (Speed, Time, Distance LOL's)


For each of the following athletes, find their average jogging speed.

a.) Keith: 19.5km in 3 hours.
b.) Jean: 8km in 1 hour and 15 minutes.
c.) Ian = 10.5km in 1 hour and 30 minutes.
d.) Lynne = 13km in 2 hours and 10 minutes.


Really? See what I have to put up with?

It probably isn't as bad as all your homework, but this is pretty hard for me. It's only, I think, C-B grade stuff like but... My target is a B... which I'm not proud of because that means I'm a D... and I don't want a D in Math for my GCSE's... DX

I get this sort of... 

...Anyway! Just thought I'd rant, again ;)


Love, TiiTii (currently writing 3rd chapter to I Wished upon a Shooting Star ((I need a better name, honestly.))) <3 <3

Oh I feel sorry for you :(
It's weird, I'm doing like exactly the same stuff as you in maths at the moment! :L
