The circumfrence of a circle is the length all arund the edge of the circle. Let's start with this question: Find the circumfrence of...

This is similar to angles in a quadrilateral, but remember, the angles always add up to 180 degrees, not 360. Let's try this question:...

There are really 3 different parts of this topic: 1: Calculating the mean (average) So, let's say we have this set of numbers: 3, 7, 4, 8...

This is where you are given 2 different equations with 2 different variables: (1) x - y = 5 (2) x + 2y = 11 Ok, so where do we start?...

Quadratic graphs follow the same basic procedure as straight-line graphs - only they're a little different: Draw the graph of y = x2 - 2x...

Welcome to the harder sets content, using Venn diagrams. So, we get this question: List the elements of a) A b) A ⋂ B c) A ⋃ B Ok,...

So, we have the set A. The things in set A are called ELEMENTS of set A. Let's say: A = {months of the year with less than 31 days} List...

This looks hard, but is actually really simple. Try this: 3/8 + 1/4. Give your answer in its simplest form. First, we need a common...

First of all, we need to know how to convert between percentages, fractions and decimals: Percentage - divide by 100 - Decimal - place...

Ok, so factorising is the opposite of expanding - you put the expression back in the brackets! (This can be used to solve quadratic...

This is pretty much the same as single brackets, except more complex. For example: Expand and simplify (x + 2)(x - 3). So, we multiply...

Right, so let's say we're given this question: Find the angle labelled x. Ok, so we know angles in a quadrilateral add up to 360 degrees....

Well, suppose we get this question: Draw the graph of y = x + 3 for the values of x -5 to 2. Ok, so we know x is the horizontal axis and...

Ok, so this is our question: Find the length of the hypotenuse. So, what's the hypotenuse? It's basically a word for the longest side in...

Right, so we get this question: Laura buys x apples. James is going to buy twice as many apples as Laura, but he decides to put 3 back....

So, the question says: A box contains 15 counters, numbered 1 - 15. If a counter is drawn at random, calculate the probability that the...

Let's say this is our question: Solve the equation x + 2 = 2x + 9 What we want is for x to be on its own, because then we can find out...

OK, so we get this question: Simplify 3x + 6x + 7x + 9 - 11. First, we need to work out which terms are "like" - for example, 3 and 6...

Let's say we're given this question: Divide £108 in the ratio 4:5. So, we now add 4 to 5. 4 + 5 = 9. Now we divide 108 by 9. 108/9 = 12....

Ok, so here is a sequence: 45, 42, 39, 36 Say we wanted to find a specific "term" of the sequence - e.g. the 10th term or the 100th term....
