... Note: You can also follow the rules for adding two numbers with different signs stated above and get the same answer. The problem 5 – 9 is the same as adding a positive 5 and a negative 9. There is no need to rewrite the problem. Example 2: - 3 - 8 This reads as “negative three minus positive eight. ...

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.
