What function could be made in order to get 4, 8, 15, 16, 23, 42?

Are Mathematics, Physics, and Computer Science degrees actually practical for making a living?

what ARE numbers?

I don't know if it is a dumb question at all, but have you a good method for studying maths? I don't have any problem with chemistry or physics, just arithmetic.
My dad speculate that I have ADD, so I can't concentrate.
The fact is, that I find really hard to understand most of the stuff and then remember and apply it to the exercise. I know it isn't anything as hard, we are studying asymptotes (I study in Italy ehw).

TD;LR Have someone of you a good method for studying arithmetics? What can I do to learn it easier?

Do you know a straight forward step by step guide explaining the rules or application of math without much wiggle room, starting from the bottom up?

We want to calculate the result of the following:

x + (-1)*x =
= 1*x + (-1)*x = (associative property)
= (1 + (-1))*x =
= 0*x = 0

This shows us that (-1)*x = -x (that is, a number multiplied by -1 gives its additive inverse). Now that we know that the result is 0, we solve the equation of x = -1:

-1 + (-1)*(-1) = 0

But for this to be true, (-1)*(-1) must be the additive inverse of -1, hence:

(-1)*(-1) = +1

Sup' /sci/, I just thought about something. You probably thought about it too, but here it is. Knowing that we commonly the Hindu-Arabic numeral system (0123456789), do you think that there is a universal numeral system? A system based on constants of our Universe instead of our fingers.

I have no major in mathematics or physics, but I'm pretty sure that the Universe has a language that makes every constants more "logic". For example, the mass of the electron would be 1 and the mass of an up quark would be 2. This is a very simplified example to show that this theoretical system would show a direct link between properties of the Universe.

Does the idea already exist? Is there a way to prove that it (doesn't) exist?

Potential-theories thread?

1 is 3, 3 is 5, 5 is 4, 4 is 4. 4 is the magic number. All numbers lead back to 4.
Why?
You may ask a number and I will give you the sequence to 4 to help you figure it out

I need help with a formula for Excel.

I need to write something for a project im doing that adds numbers a certain way. the first number is 3. Next, it takes 3, and then adds 3 plus 6 (9). the next cell, its takes 9 and adds 3 + 6 + 9 (18) and so on. I need to this this for 91 cells.

I have no idea what this would be called or how to do so. Any help would be great.

Hey /sci/, what would be the correct way in math to symbolize counting of elements in a set based on a certain criteria?
Eg you have {1, 2, 3, 4} and you'd like to write down the count of elements which > 2

is it numberwang y/n?

Why is the world in base 12? Base 12 would clearly be more practicle due to the fact that you can have thirds and fourths.

Dear /sci/, I'm a mathematical illiterate and I'm looking for tips on how to learn math, inb4 school because It's not doing any good. Specifically looking for sites or tips on this.

what do you think /sci/?

What's the luckiest number?

how can an electronic random number generating program work?

If I start two programs, each one on an identical computer, how is it possible that they don't each generate the same number?

Using this set and mathematical notation

<span class="math">N={0,1,2,3,4,5,6,7,8,9}[/spoiler]

Come up with the biggest number you can.

No English words are allowed (that means you can't just say "graham's number" or "googolplex").

No infinities or limits are allowed either.

Good luck /sci/borgs

do numbers have vowels?

How do I keep up with my maths skills? I used to do quite well at math related subjects but last few years my brain has slowed down. It takes a good few seconds for me to calculate simple addition/subtractions in my head but a few years ago this would have been done in an instant. Am I just getting old?

So guys when you think about numbers do you imagine them in color ? For me these are the colors :
1-white
2-red
3-yellow
4-blue
5-pink
6-black
7-green
8-orange
9-brown
0-black

Hey /sci/, dyscalculiafag here.

I have a math learning disability and as a result I have about the general math ability of a seventh grader, and the mental math ability of a third grader. What is the best way to help me learn math? I have wanted to be in the medical profession for awhile but I don't know if I'll be able to handle the math courses required.

tl;dr: general math learning recommendations for someone with very little math ability

Mathfags, please explain to non-mathfag why .99999999999999_ = 1
I took calc 1,2 dfq, blah blah blah and have read the proofs of the net.

What I need is someone to explain to me why an infinite amount of something = unity. An infinity of something, no matter how small, is still infinity, not one (zenos paradoxes come to mind). .9999999999999 seems to asympototically approach 1 but never get there. Is it because mathematics without units is only theoretical ergo meaningless?

I know I will get a mathfag rage aganist me, but perhaps in that rage someone will help explain this. I know the PROOFS, philisophically it makes no sense, and just because a proof says so in a logical system doesnt mean it is SO (goedels incompleteness theorem).

Ok, /sci/ do you worst:
