In this video we look at the basics of algebra, focusing on the notation that is used. In algebra we use symbols to represent numbers. These symbols are called variables. Some reasons for using symbols instead of numbers is that the symbols, or variables, can represent unknown quantities and for showing formulae like the area of a circle. Instead of writing a X b we remove the multiplication sign and just write ab instead. Two letters next to each other or a number and a letter, means those things are multiplied together. We use a curly x for the letter because otherwise it looks like a multiplication sign. Instead of the division sign, in algebra we usually write it as a fraction. Numbers are usually left as fractions rather than as decimals. Our teachers and animators come together to make fun & easy-to-understand videos in Chemistry, Biology, Physics, Maths & ICT. VISIT us at www.fuseschool.org, where all of our videos are carefully organised into topics and specific orders, and to see what else we have on offer. Comment, like and share with other learners. You can both ask and answer questions, and teachers will get back to you. These videos can be used in a flipped classroom model or as a revision aid.

Learn the basics about the process of measuring the heat of chemical reactions or physical changes as well as heat capacity. What is Calorimeter? How does it measure heat? Find out more in this video! This video is part of 'Chemistry for All' - a Chemistry Education project by our Charity Fuse Foun
You might have noticed that if you are trying to boil a lot of water it takes longer than if you only wish to boil a small amount of water. This is all because of something called ‘heat capacity’. Keep watching to learn more. Before we get into the details, it is important to realise that there i
An ecosystem can be defined as a large, highly interconnected area of the planet that is composed of several different biotic and abiotic components. A good example of an ecosystem would be an entire forest or mountain range. JOIN our platform at www.fuseschool.org These videos can be used in a f
