Firstly, the following question only applies to those who are good at memorising lots of numbers i.e. irrational numbers to so many decimal places, constants in science etc...

When you remember a long number, how do you "see" it in your head? Do you just remember the numbers without really seeing anything, or do things come into your head?

I have a strange thing happen to me when I'm remembering numbers. I know 200 decimal places of pi at the moment, and when I recall them, I see shapes in my head, but they seem four-dimensional...? So I cannot explain how they are shaped, because they're not 3-D. I have a different shape for every group of five numbers in pi. This also helps me do quick mental arithmetic, as the numbers seem to coalesce to give the answer. Sometimes I even get a question in maths and I just do it, there and then, without thinking of HOW to do it. Its just that the shapes... warp themselves?

I do not necessarily memorize long numbers, but I memorize lots of shorter ones. For example, I have memorized the atomic masses of approximately forty elements on the periodic table, though I only go out as far as they are accurate and practical. I also have both pi and e memorized out to about ten digits after the decimal place, give or take a few.

I am able to do math mentally better than I am able to do it on paper and I only use paper for something that I either have to show my work or it is long and I will need to record my answer.

I can understand this well! I have learnt the melting and boiling points of 20 or so elements so far. I've only just started, but its very useful.
And the working out - I find myself having to write down 3 times more than I really need to. I only write down my "working out" because the teacher becomes narky if I don't.
Perhaps you should try memorising pi - you may be very good at it.

Perhaps... I usually only memorize things if I have a use for them or if it is in an area of special interest (ie epidemiology and diseases or ... a new one, the toxicity of chemicals).

By the way, I like your avatar... or lack thereof. ;)

And how about my new one? Oh yeah!

On the numbers thing, I have trouble remembering the first four times tables, so if you expect me to remember countless numbers decimal-wise, you're better off asking Forrest Gump.

if your saying its 4-d a

Algorithm diagram is 4-d, Tesseract Hypercube, fourth dimension is often a representation for bounded transformations, tesseract can be unfolded into eight cubes, just as the cube can be unfolded into six squares. An unfolding of a polyhedron is called a net. There are 261 distinct nets of the tesseract..

I understand that. I've been onto chemical reactions, organic compounds used in every-day use and melting/boiling points of chemicals.

As for actual texts, I've been reading about infectuous diseases and mechanisms of reactions in chemistry.

i always look at numbers as patterns.
for example:
PI: 3. 141 5926 535 8 979 323 84 626 43 383 ...
do you see the pattern i see?
141, 535, 979, 323, 626, 383...

this IS a pattern, but i always see it in places you normally wouldn't
0, 1, 1, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 600....
at one point i was obsessed with these. YOU CAN FIND IT EVERYWHERE!! !! !! !

Tsk tsk you missed out the "2" in the last pattern!

I can see your pattern in pi though.

I ADORE Pascal's triangle in different base systems though.
