In this video we are going to look at how to change the subject of a formula, when the subject appears twice. We have already looked at how to change the subject in another video, so you may want to watch that first. We always use opposites: adding and subtracting, multiplying and dividing, squaring
In this video we are going to look at rearranging straight line equations to find the gradient and y-intercept. Straight lines follow the equation y=mx+c, where the m is the gradient and the c is the y-intercept. But straight line equations aren’t always written out in this nice form. Sometimes we h

In this video we’re going to look at how we can solve equations using a method called inspection. 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
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
Learn the basics about the atom economy principle of Green Chemistry, as a part of environmental chemistry. A reaction with a high atom economy is one where all of the atoms in the reactants are included in the final, desired product. Such a reaction would have little, if any, waste produced. A
Every operation has an opposite. With functions the opposite is called the inverse function. It undoes the function and returns you to the initial input. There is a simple process to follow to find the inverse of any function which we look at in this video. 1) Start by writing the function as y=
We can derive expressions and equations from sentences, and also we can derive formulae such as area and volumes, or quadratics. In this video, we're going to look at deriving formulae. You are usually given information in a diagram or sentences and asked to "show that". Ignore the "show that" as th
Learn the basics about balancing equations, as a part of chemical calculations. The law of conservation of mass states that no atoms are lost or made during a chemical reaction. There are different ways of arranging the atoms. Chemical reactions are about rearranging atoms. Chemical reactions can

Click here to see more videos: https://alugha.com/FuseSchool Quadratics can be solved in different ways: factorising, quadratic formula, or by completing the square. In this video, we are going to look at how to use the quadratic formula to solve quadratics. Quadratics can’t always be factorised. H
