What's the easiest way to calculate all combinations of numbers, in sets of 5, that eqaul n. For instance, say n=20. Sum combinations would include:
20+0+0+0+0
19+1+0+0+0
....
5+5+5+5+0
....etc

Is there a mathmatical formula that would lead me to those sums without going through all combinations individually? I'm not a math whiz, so details will be GREATLY appreciated.

Please let me know if you have any further questions!

Thanks!
--Dan

I know that it's easy to find the symmetries (reversible, fully amphicheiral, negative amphicheiral, chiral) for prime knots; i.e. the KnotInfo search result page here gives them:

http://www.indiana.edu/~knotinfo/results.cgi?knots=3-6&knots=7&knots=8&knots=9&knots=10&name=1&symmetry_type=1&full_symmetry_group=1&option=html

Is there any such table of symmetries of prime links and/or composite knots and/or composite links?

(as always, please correct me if I'm using bad/wrong terminology or asking a bad question.)

solve for the variable:
6x2 - 6x - 36 = 0
(6x2 means 6x squared)




solve the following inequalities:

-6x<18

-16x+4<-8x



factor by undoing foil:

x2+5x+6

(x2 means x squared)

x2-5x-14

i used to know all these formulas such as (a+b+c)^3,
(a+b)(a-b), etc.

I'm not sure what they are called but could someone supply the list to me???

We know the answer (from the answer sheet), but can't understand how to get to it. It's driving us nuts!

Example 23/4^2/7-5 -(6) I am not sure I did this right -14

How do you solve this?
how do you solve the d---- 5d-3 =7d+9
how do you solve the a---3-2a+10-3(2a-3)
Any tutors available for Algebra....

relates each number to the previous number....like if i had 2,4,6,8,10..i know that the next number is 12 and i know that the formula is 2n, but i need a recursive formula to show how to get from one number to the next...like this:

recursive: a(sub n)= a(subn-1)+2
in other words, to get to the next number, take the PREVIOUS NUMBER and add 2...

once again, i know the next number is 55 and i know that the formula is n(2n+1) or 2n^2 +n.....


does anyone understand what im trying to say....
