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.

Respiration is the chemical process that supplies the body with energy for all other life processes: growth and repair of cells, muscle contraction, protein synthesis, sending nerve impulses, absorbing molecules in active transport to name just a few. It happens in ALL living cells, not just anima
An acid is a substance that will dissociate in water to give a proton (or H+ ion) and a conjugate base. An acid is considered to be strong if dissociation nears 100%, and weak if dissociation is usually less than 1%. In this lesson, we will learn about strong alkalis and weak alkalis. An alkali
