Strategy for Solving Algebraic Equations Example: 3(x
... 2) Given info: Sum = 72. Each integer is 2 units apart. 3) Work out a plan. Let variables represent the unknown numbers. n = 1st number, n + 2 = 2nd number, (n+2) + 2 = 3rd number, which can be simplified to n + 4. Use these variable expressions in equations using the given info. “Sum” means additio ...

... Big Idea #3: A logarithmic function is the inverse of an exponential function. You can identify an inverse function by comparing its graph to the graph of the original function. The two graphs are a reflection of each other across the line y = x. Exponential function: f (x) = bx The base b is any nu ...

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.
