You're probably aware of the trick to find whether a number is divisible by 9 - if it's divisible by 9, so is the sum of its digits. The same thing works for divisibility by 3. For example:
12345's digits add up to 1+2+3+4+5 = 15 which is divisible by 3, so 12345 is divisible by 3 (it's 4115×3).

Partitions into Consecutive Integers
For any positive integer N, let f(N) denote the number of ways in
which n can be expressed as the sum of consecutive positive integers.
For example, since 9 can be expressed as 2+3+4 and as 4+5 and as 9,
we have f(9)=3.

Twist or Bust
MAA Online know it too.
The image to the left indicates why I could not resist my title. It shows a kink put into a long pipeline to prevent the pipe from fracturing when it expands in hot weather.
Which brings me to the mathematics. Imagine there is a stretch of pipe a mile... | 4 | [

Commutative Algebra
Ring Homomorphisms
A mapping $f : R \rightarrow S$ where $R, S$ are rings is a ring homomorphism if
1. $f(1) = 1$
2. For all $x,y\in R$ we have
\[ \array { f(x+y)&=&f(x) +f(y) \\ f(x\cdot y) &=& f(x)\cdot f(y) } \]
It is easily verified that if $f$ is a ring homomorphism, then:
1. $f(0)=0$

finding the min distance between two vectors
Hi there,
Im trying to find the minimum distance(sum of their radii) between two circles.
The circles have position vectors a radius and a velocity... | 4 | [

Divisible Consecutive Sums
Problem
By adding four consecutive integers it is possible to make different totals. For example, 16 + 17 + 18 + 19 = 70, which is also divisible by 10.
How many of the numbers under 100 that are divisible by 10 can you make by adding four consecutive integers?
