A surd is a square root which cannot be reduced to a whole number. Surds are irrational; they are decimals that never end and never repeat, so cannot be written as fractions. Leaving a number in it's surd form is easier and more accurate than writing and rounding the decimal places. We see surds
In this video we are going to have a quick look at adding and subtracting surds. 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
In this video we are going to look at how to do percentage increases and decreases, using multipliers. You should already know what percentages are, and how to find them. VISIT us at www.fuseschool.org, where all of our videos are carefully organised into topics and specific orders, and to see what

Algebraic fractions are simply fractions with algebraic expressions either on the top, bottom or both. We treat them in the same way as we would numerical fractions. In part 1 we saw how to simplify, and add and subtract algebraic fractions. We discovered that algebraic fractions follow the same pri

Polynomial division without remainder simply explained - theory, examples and exercise - Math Upper School & University. In polynomial division you need three steps: Divide, Multiply, Subtract. Without remainder means that there must be a 0 under the last streak. With the help of two examples and ex
Creating tree diagrams + calculating with them as well as path rules 1 and 2 explained simply. Today we will show you the basics of how to create a tree diagram, what you can see from it and how to calculate with it. To get the probability for a very specific experimental outcome, you need to multip

Polynomial division with remainder simply explained - theory, examples and calculation - math high school & university. Polynomial division requires three calculation steps: division, multiplication, subtraction. With remainder means that a number remains below the last bar. Using examples and exerc

Before we get started, I am assuming you already know how to solve equations by balancing: you must do the exact same thing to both sides. So lets have a look at how to solve equations inv
