### Consecutive Numbers

An investigation involving adding and subtracting sets of consecutive numbers. Lots to find out, lots to explore.

### 14 Divisors

What is the smallest number with exactly 14 divisors?

### Summing Consecutive Numbers

Many numbers can be expressed as the sum of two or more consecutive integers. For example, 15=7+8 and 10=1+2+3+4. Can you say which numbers can be expressed in this way?

# Crawl Around the Cube

##### Stage: 3 Short Challenge Level:

At $Q$ the ant can choose first to go left to $T$, then right to $W$. Otherwise, at $Q$ he can go right to $R$ and then left to $W$.
$W$ is the corner diagonally opposite to $P$ and is reached by either route after three edges (and no fewer). So after exactly three more edges, the ant must reach the corner opposite $W$, that is, $P$.

This problem is taken from the UKMT Mathematical Challenges.
