GCSE MATHS: Number

There's more than a few ways to divide a whole. Fractions, decimals and percentages are some of the ways we think about ways to separate numbers. This video should help explain.

FRACTIONS, DECIMALS, AND PERCENTAGES

This mind map will help you understand the different types of fractions we use in mathematics. Improper fractions, unit fractions, equivalent fractions, numerators and denominators are here.

Decimals are often used as a means of measurement. Place-values quickly illustrate the relative values of decimals at different points on the number line.

Decimal numbers have two parts: a whole number part and a part that is less than 1 . The two parts are separated by a decimal point.

Before we move on to the next section, take a moment to look at this youtube video which explains the next topics of structure and calculation.

STRUCTURE AND CALCULATION

Numbers can be described as being natural, integer, rational, irrational, real and ordinal. These flashcards will explain what we mean by each of these terms and help you learn the difference between them.

Integers are whole numbers that can be expressed positively or negatively. The operations performed on integers are addition, subtraction, multiplication and division.

Two wrongs do not make a right...but, two minuses can make a plus when you multiply them together. Here are some basic rules when dealing with problems with two or more integers.

The title says it all. Here are 11 strategies for integers. Basic substitution, completing the square, trigonometric identities, eliminating square roots, separating fractions and others.

In this context, when we say powers, we are referring to cubes and cube roots. When we say roots, we are referring to squares and square roots.

A Surd is a number that cannot be shown as a decimal, as it has a never ending, never repeating set of decimals. π (Pi) is the most well known example of a surd.

Okay, let's review. Here are ten short questions which will help revise your knowledge of integer, cubes, cube roots and other problems we have encountered. Good luck.

Sometimes complicated subjects can best be explained with the help of a number of fluffy hand puppets. Here's a short video from the makers of Sesame Street to explain measure and accuracy.
