The area of a circle can be derived by the formula A = πr2. In this tutorial you will learn how to apply this formula to an example. For explanation on how this formula works read Continue reading “How to Calculate the Area of a Circle? | Geometry | Maths | Tutorial”
You may not know this but there is no way of calculating the area of a circle exactly. The area of a circle is calculated by splitting the circle into many right-angle triangles and then calculating the area of these triangles. As you know triangles have straight lines and circles are curved therefore Continue reading “Area of a Circle – Proof | Geometry | Maths | Tutorial”
You may come across a simple maths questions with a mixture of brackets, orders (powers), division, multiplication, addition and subtraction all at once. You may think to yourself where do I start, this is where Continue reading “BODMAS – The Order Of Mathematical Operations | Maths | Tutorial”
This post will show you how you can turn a little bit of maths in to a magic trick that you can try with your friends or family. Continue reading “Maths Magic Trick | Maths | Algebra | Tutorial”
This theorem proves that for a right angle triangle, the area of the square on the hypothenuse (the longest side or the side opposite the right angle) is equal to the sum of the area of the squares on the sides adjacent to the right angle.
This tutorial will look at the difference between combinations and permutations without replacement and how to calculate these. This post expands on concepts learned from the Emma’s Dilemma permutations tutorial. Continue reading “Combinations & Permutations Formula Simplified | Maths | Tutorial”
In this scenario we look at two names EMMA and LUCY, we want to find out all the possible arrangements the letters of their name can be used to make this is known as permutations. We will also learn to use a formula that will help calculate how many different combinations there are without having to write them down manually this is especially useful if there are 100’s of possibilities.
