Magoosh	How many three-digit numbers are there such that all three digits are different and the first digit is not zero?
Magoosh	The times and amplitude of neap tides, the low amplitude tides that occur during first and third quarters of the lunar month, are due to not only the cancellation of the tidal forces of the Sun and the Moon but also a host of factors—amphidromic systems, the shape of coastline, and near-shore bathymetry—any of which can lead to significant fluctuations in the time and amplitude of neap tides only miles apart.

Magoosh	One of Hannibal's successful battle techniques was charging wild elephants directly at the Roman armies, trampling infantry and inducing disarray in the ranks, but Scipio's successful counterstrategy was to command that his men should part, creating channels that allowed the elephants simply to pass through, with them killing the elephants behind his ranks.
Magoosh	In the figure above, JKLMN is a regular pentagon. Find the measure of ∠KQL.
Magoosh	A newly released study on the tectonic plates forming the Pacific basin indicates that by the time they had shifted even a few miles, a vast percentage of the coastline which is currently home to major world cities, because of global warming, will have already become entirely submerged.
Magoosh	If ABCD is a rectangle, BC = x and AB = 2x, then the circumference of the circle, in terms of x, is
