How do computers count numbers
... How do computers count numbers? Imagine that you can only count with the digits 1 and 0, how would you be able to add, subtract or do anything else that you normally do with numbers whose digits go from 1 to 10? A computer can only store a 0 or a 1 but it can store lots of them. E.g. the number 123 ...

The Mathematics 11 Competency Test
... When we write down a formula for some quantity, y, in terms of another quantity, x, we are expressing a relationship between the two quantities. For example, if we use the symbols y = the area of a square and x = the length of one side of the square, then the formula y = x2 tells us the relationship ...

... The diagram below shows the Sieve of Eratosthenes for integers less than or equal to 100. First we write down all the integers between 2 and 100. Since 2 is prime we cross out all the multiples of 2 or the even numbers apart from 2 itself. The first of the remaining integers is 3 so it must be a pri ...

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.
