Equations are used everywhere: in computers, business, internet searches, medicine to name a few examples. Which is why we study them a lot in Maths. We have names to describe the different parts: coefficients, variables, constants and exponents. A variable is a symbol for a number we don’t know yet. It is usually a letter. A number on it’s own is called a constant. These are different to the numbers in front of variables: these are called coefficients. They are different to constants, because coefficients always multiply by a variable. A number and a letter is a coefficient and a variable. But a number on it’s own is a constant. If a variable doesn’t have a coefficient in front of it, it means the coefficient is 1. But in algebra we don’t write the 1: 'a' instead of '1a'. Sometimes we can even have letters to represent coefficients: ax + by. Exponents tells us how many times to multiply the value by itself. The exponent has a few different names: exponent, index, power.

Interest is the amount charged by a lender to a borrower. It means that if you borrow some money from a bank, you have to pay back more than the money you borrowed. Equally, if you have a savings account and deposit some money, the bank will pay you interest as a sort of thank you for saving with th
In this video we are going to look at a few different ways in which plant hormones can be used. Plant growth hormones (auxins) can be used as selective weedkillers. The selective weedkillers contain growth hormones, that cause the weeds to grow really quickly. This means the weed is absorbing nutr
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 this video we look at how to simplify algebraic fractions, and how to add and subtract them. VISIT us at www.fuseschool.org, wh
