... is has a lower cost than one-way trip. Let cXY be the cheapest round trip from A to B to A. Let cYX be the cheapest round trip from B to A to B. The problem of buying flight tickets now becomes a problem of eliminating characters from the string for a given cost: cX to eliminate a single character X ...

... Let us now remove from (b) a single line segment to arrive at the figure in (c). The Euler formula still stands because, along with the removal line segments, the number of faces also decreases by one. We can conclude that the Euler formula also applies to a polyhedron containing multiply-connected ...

... around the earth varies directly as the radius of the orbit (from the center of the earth) and inversely as the orbital velocity. If a satellite completes an orbit 710 miles above the earth in 17 hours at a velocity of 38,000 mph, how long would it take a satellite to complete an orbit if it is at 1 ...

Elementary mathematics
Elementary mathematics consists of mathematics topics frequently taught at the primary or secondary school levels. The most basic topics in elementary mathematics are arithmetic and geometry. Beginning in the last decades of the 20th century, there has been an increased emphasis on problem solving. Elementary mathematics is used in everyday life in such activities as making change, cooking, buying and selling stock, and gambling. It is also an essential first step on the path to understanding science.In secondary school, the main topics in elementary mathematics are algebra and trigonometry. Calculus, even though it is often taught to advanced secondary school students, is usually considered college level mathematics.
