Adding and subtracting fractions involves the process of making the denominators the same. Remember, whatever is done to the denominator has to be done to the numerator. When the denominators are the same you you add the numerators.

The aim of solving equations is to get the unknown on its own. Drawing a line down from the equals sign allows you to make sure that whatever you do to one side of the line you do to the other. Always remember the key to this is the opposite sign.

Expanding bracket with surds use the same method as expanding brackets with algebra. The only part that is different is when you multiply two surds together that this will become a whole number.

Rationalising surds is the process of changing a fraction with surds in the denominator so that there is only a whole number. This is done by multiplying. both the numerator and denominator by the terms in the denominator but be careful when there is more than just a surd.
