How to multiply brackets
Hopefully you already know how to change a fraction to a decimal.
For instance ²⁄³ =2 ÷ 3= 0.6666… This is a recurring decimal. But changing a recurring decimal back to a fraction is a little more complicated.
UK maths teacher have produced a great video on this.
If you prefer a written explanation Study maths have produced a good introduction of how to convert a recurring decimal to a fraction.
Here is a useful quiz from amrdolan to test your knowledge of gradients.
This is one in a large series of short videos from NCETM showing how people use maths at work. See the others here.

A jigsaw to revise linear graphs and their equations. Do you remember y=mx+c? m is the gradient, c is the intercept on the y axis. If you have forgotten this look here first.
Some of these equations need re-arranging so you can find the gradient and intercept, but others are already in the y=mx+c format.
I think this is one of the best jokes yet! Do you get it?
This jigsaw will help you revise simplifying expressions, inequalities, expanding brackets and factorisation. Is this the worst joke yet?

If you can factorise a quadratic that is the easiest way to solve it. Some quadratics don’t factorise, so then we can use the formula. This video from jayates shows how to do it. If you are studying GCSE Higher you are currently given the formula in the exam so you don’t have to learn it off by heart, but don’t forget to refer to the formula sheet at the front of your exam paper when you need it.
Maths is fun explains this well but don’t worry too much about the “imaginary numbers” at the end. If you are doing Higher you don’t need to know that yet.
Here is a worksheet that you can print off and practice solving quadratics with the formula.
This video shows you how to solve simultaneous equations using algebra.

Surds are numbers left in square root or cube root format. We leave them as surds because in decimal form they go on forever, so it uses up lots of ink to write them and accuracy is quickly lost. There are lots of tricks to simplify surds and these two videos from maths520 show them clearly. This topic is important for Higher GCSE students.
