... An exact or terminating decimal is one which does not go on forever, so you can write down all its digits. For example: 0.125 A recurring decimal is a decimal number which do not stop after a finite number of decimal places, but where some of the digits are repeated over and over again. For example: ...

... We can only add/subtract fractions when they have the same denominator, so change every term so that it has the same lowest common denominator Where there are fractions in the numerator/denominator multiply throughout by the lowest common denominator to eliminate these ‘fractions within fractions’. ...

... • Relative frequency is the number of times that the event is likely to happen • e.g. a RF of 0.2 means it will happen one fifth of the time. • How many times will the red counter appear in 200 goes if the relative frequency is 0.3 • Answer 0.3 x 200 = 60 • The relative frequency can be found by exp ...

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.
