insane to comprehend as Eratosthenes did it over 2000 years ago without modern tech 
he even made columbus look like a fool 1700 years later as columbus thought the calculation was out ^_^
to me that is "insane" (another term for impressive... its not me saying he was "insane" as in crazy)

oh ok
i kinda get it now
i was hoping there was some simple formula of working this out
im gonna give up on it as this is way above my math and science knowledge now and im getting more and more confused
ty for your help guys 
i do appreciate it
i still dont believe the earth is flat and personally i think the whole idea of a flat earth is ridiculous! but i do see they make some good points in there arguments of claiming its flat... <3

im totally confused about this 8" drop now...
bobbym how did you get 1.2 miles?
using google converter 8 inches = 0.000126263 miles
then multiplying that by 100 gives you the total drop of 0.0126263 miles over 100 miles
have i miscalculated?
i admit im not good at conversions and i think ive messed up somewhere
ive already hit him with the gravitational pull and how you can see farther the higher you are (distance to the horizon)
reading that bit about Eratosthenes is insane! ty bob bundy "the more you know"

having a big debate about this "flat earth" rubbish
person im talking to is claiming that the suez canal is 100 miles long so it would need locks in it to counteract the earths curve if the earth was round...
"The Suez Canal connecting the Mediterranean with the Red Sea is 100 miles long without any locks making the water an uninterrupted continuation of the two seas."
my side of this debate is 100 miles is way to small a distance to notice any difference when it comes to the size of the earth.
i googled it and the earth circumference is 24000 miles.
not sure if we need these but ill add them in case... earths radius is 3,959 miles km and diameter is 7,917.5 miles.
how do i work out how many degrees 100 miles is over a 24000 miles circumference?
im guessing its gonna be like 0.5 of a degree
24000 /100 /360=0.6666666667
is that the degree or have i messed my math up?
and how would i then work out how much of a drop that 100 miles would have from start to end?
im guessing it only will be acouple of inches

ok matir thats just confused the hell outta me 
lol

just got the link to where this guy claims how to solve maths problems... http://www.slate.com/articles/health_and_science/science/2013/03/facebook_math_problem_why_pemdas_doesn_t_always_give_a_clear_answer.html
*facepalm*
so changing the sum to make your answer right... we now do this in math??? i dont think so!
ill stick to my pemdas!

knew it couldnt be true so thank you both ^_^ just think of all the scientific calculators that would obsolete
i guess there really isnt anything other then silly posts on facebook! i more then anything wanted confirmation on this before "I slice open his gizzards and leave him for the gators" (can i nick that btw? that made me lol ^_^ )
doesnt seem like i can like posts on here or id of done so
again thank you both so much ^_^

First time making a post on this forum but i love the mathisfun site
ok on one of these silly facebook posts they ask
20+30x0+1=?
a)1
b)21
c)51
d)0
clearly by using "Please Excuse My Dear Aunt Sally" you get 21
20+(30x0)+1=
20+0+1=
20+1=
so i post "easy! b 21 Please Excuse My Dear Aunt Sally"
to what i get this reply....
"I understand your point, and according to "older" theory, the "30x0" would be the first operation in this equation. However, another similar equation has circulated in recent years in which mathematicians have explained that the order of operation has changed. In this new way, the order is based on the leftmost operator "20+30". The old standard would equate to "1", whereas the new standard would be "21". I think the entire math world is confused. LOL"
so my question is... is there any truth to this? it seems very far fetched
