... We have talked about the look of a 2nd degree equation and we have called it a parabola. Here are some characteristics. 1. The domain is all real numbers, and the range is either (, max) or (min, ) . 2. If the coefficient of x 2 is positive, it opens up and if the coefficient is negative, it ope ...

Consecutive Odd Numbers
... Plan to investigate and solve: I will solve an equation to find the least of five consecutive odd numbers whose sum is 3055. I will choose the variable x to represent the least number of the five numbers. My equation will be x + (x+2) + (x+4) + (x+6) + (x+8) = 3055. If x is a odd number , the next c ...

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.
