Practice & Revision (1)
Algebra Refresher - Interactive version
An interactive version of the refresher booklet on Algebra including links to other resources for further explanation. It includes revision, exercises and solutions on fractions, indices, removing brackets, factorisation, algebraic frations, surds, transpostion of formulae, solving quadratic equations and some polynomial equations, and partial fractions. An interactive version and a welsh language version are available.
Quick Reference (8)
Addition and subtraction
Fractions involving symbols occur frequently. It is necessary to be able to add and subtract them. On this leaflet, we revise how these processes are carried out. An understanding of writing fractions in equivalent forms is necessary.
Fractions
The ability to work confidently with fractions, both number fractions and algebraic fractions, is an essential skill which underpins all other algebraic processes. In this leaflet, we remind you how number fractions are simplified, added, subtracted, multiplied and divided.
Mathematical Symbols and Abbreviations
This leaflet provides information on symbols and notation commonly used in mathematics. It shows the meaning of a symbol and, where necessary, an example and an indication of how the symbol would be said. For further information from mathcentre resources, a search phrase is given. This Quick Reference leaflet is contributed to the mathcentre Community Project by Janette Matthews and reviewed by Tony Croft, University of Loughborough.
Multiplication And Division
Fractions involving symbols occur frequently. It is necessary to be able to multiply and divide them. On this leaflet we revise how these processes are carried out.
Percentages
The use of percentages is common in many aspects of commercial life. Interest rates, discounts, pay rises and so on, are all expressed using percentages. This leaflet revises the meaning of the term 'percentage', and shows how to calculate percentages, and how to convert expressions involving percentages into alternative forms.
Ratios
Ratios are an alternative way of expressing fractions. This leaflet will revise ratio calculations
Sigma notation
Sigma notation provides a concise and convenient way of writing long sums. This leaflet explains how.
Teach Yourself (4)
Decimals
In this unit we shall look at the meaning of decimals, and how they are related
to fractions. We shall then look at rounding to given numbers of decimal places
or significant figures. Finally we shall take a brief look at irrational numbers.
Percentages
In this unit we shall look at the meaning of percentages and carry out
calculations involving percentages. We will also look at the use of the
percentage button on calculators.
Ratios
A ratio is a way of comparing two or more similar quantities, by writing two
or more numbers separated by colons. The numbers should be whole numbers, and
should not include units.
Sigma notation
Sigma notation is a method used to write out a long sum in a concise way. In
this unit we look at ways of using sigma notation, and establish some useful
rules.

Fractions - adding and subtracting
In this unit we shall see how to add and subtract fractions. We shall also see
how to add and subtract mixed fractions by turning them into improper
fractions. (Mathtutor Video Tutorial)

Fractions - basic ideas
What are fractions? Fractions are ways of writing parts of whole numbers. For
example if we take a pizza, and divide it up equally between 4 people, each
person will have 1/4 or, written in words, one quarter of the pizza.
