Mathematics is not just about being good at arithmetic and algebra but it does depend
on them. The better your skills in arithmetic and algebraic processing the better
will be your mathematics.
You should be able to perform “long multiplication” and preferably “long division”.
You should be very confident with negative numbers. Click “skills practise” to use
the negative numbers pages
You must be able to calculate with fractions. Click “skills practise” to use the
interactive fractions page.
You should know the prime numbers below 30 and the first 15 square numbers. Knowing
the first four or five cube numbers will also help. Click on “explore ideas” to find
out about prime numbers, the Goldbach conjecture and the fundamental theorem of arithmetic.
Also on “explore ideas” you can find out about the Fibonacci numbers and some related
The “maths tools” section has interactive pages for factoring numbers in different
ways, simplifying simple algebraic expressions and solving simple equations, perform
binomial expansions, illustrating the basic ‘trial and improvement’ method, exploring
quadratics and long division including polynomial division.
The “maths videos” pages include video solutions of common GCSE and A level problems.
There are areas for “students” and “teachers” which include simple resources and
