Algebra and graphs are an integral part of our lives. If the man sells his oranges for 50 cents per kilo, how much would you have to pay if you need 3 kilos? A very common situation and every time you use algebra to make sense of it. You will mentally construct an algebraic equation to work out the price you will have to pay. You do this probably without even noticing it. We can plot this information in a graph which will help us, by providing us a visual representation of the situation, to work out the total price of a certain amount of oranges in the future. During your maths revision you will encounter a lot of algebra and many graphs. Many maths problems, activities and example questions deal with algebra and on many occasions you will be asked to either draw or interpret a graph. Have a look at the following links where I will explain to you all you need to know about algebra and graphs to pass your IGCSE GCSE maths exam. When studying those links you will discover how important our understanding of algebra and graphs is to make sense of the world around us. I will see you there!!
