Hi guys,

I've tried googling this but I've had no joy and I know there's Maths geeks in here.

I'm trying to workout how I would find the end result of the following:

Start with 5,000 then divide it by 1.5, and the result then multiplied by 1.53, then that result by 1.53 and so on. I need to find out what the end result would be after 104 times of doing these sums and I don't particularly feel like doing each sum 104 times

Thanks guys

Raise it to the power of 104. So (5000/1.5)*1.53^104.

Why do you need to know this and why do I feel like I've somehow helped you cheat on your homework.

Awesome. Thank you, I was struggling with that.

I'm due a bonus and being stationed in America I've worked out I can send it back to the UK and bring it back to the states and potentially make a reasonable amount of money from it just from the fluctuating exchange rate

I've not done maths for a while so I'm fully prepared to be laughed at for getting it horribly wrong..... but would it not be (5000/1.5)*1.53 and then using a scientific calculator ((ans/1.5)*1.53)*103

I don't know how you'd express the 'answer' function on a calculator as an equation though.

1 does not equal .9 repeated

No worries!

No worries!

Yeah, I can't seem to get that to work on a calculator

#8

OK are you using a scientific calculator?

Also how exactly did you come up with that equation and where did you get the numbers from/what do these numbers I've just unquestioningly plugged in actually mean?

#9

1 does not equal .9 repeated

If .333 recurring is a third, and 3 thirds are a whole, then logically .999 recurring equals 1.

There's a video on YouTube 9.999 reasons why .999 equals 1.

#10

or you could search the 200 page circus of a thread we had here about it

1 does not equal .9 repeated

It's too early for this shit.

#13

I stand by my former reasoning.

Theoretically .9 repeated does not equal 1, but in all practical aspects it does.

...do you know what numbers are? Not those bizarre scribbles we use to notate them, but numbers in-and-of-themselves?

#15

lol

#16

Guys I have two candy bars. One for myself and then two more people get a full candy bar each. Because 2=3 because lol math isn't real.

#17

Guys guys guys we sorted this out a long time ago

In my applied mechanics earlier in the week, like 80% of the class got all of the questions wrong because they rounded 49.98459 to 50 ect. and got a load of rounding errors, and then carried them forward. Quite amusing really, I don't get what's so hard about leaving stuff as 6Pi or as a fraction

but yeah, theoretical maths and mechanical maths are different, very different

#19

lol, "maths."

#20

people that like math tend to be lousy people from my experience

0.888888... in no way, shape, or form could ever be equal to 0.999999...

That's just nonsense.

#22

people that like math tend to be lousy people from my experience

agreed

#23

0.888 = 0.999, just erase the bottom left parts of the 8s

#24

0.888 = 0.999, just erase the bottom left parts of the 8s

I stand corrected

ok so there's this cool super secret trick to get free money

basically we both put $20 in a box so there $40 in the box

then i sell the box to you for $30 dollars and we both make $10

then repeat for infinite money

this would be funny if it weren't terrifying.

it's how the super rich get richer

it's just that they can afford to do it with larger sums of cash and bigger boxes

should I take this personally.

are you a lousy person

well it would be 5000 * (1.53/1.5)^103 in standard notation

#32

Maths are just silly logic games anyway

#33

people that like math tend to be lousy people from my experience

Seconded.

Math people, do the world a favor and be cool.

#34

i hate maths and i'm an awful person

#35

i'm alright

#36

are you a lousy person

Well I like maths... please define parameters of 'lousy'

#37

Well I like maths... please define parameters of 'lousy'

if you have to ask you are lousy

#38

are you a lousy person

Confirmed.

#39

Well I like maths... please define parameters of 'lousy'

i'm in my 2nd year of maths @ uni now and i still like maths. i'd rather do maths than any essay-based subject, it's a very unique subject and should be considered by anyone that has a nice understanding of it.

I used to do this, such a n00b error
