Maths E.G. is delivered to you free of charge under a Creative Commons licence. You may use it as often as you like for any educational purpose. Each question in the database will generate thousands of examples, each with fully-worked solutions which you are invited to study. You can set up the fonts sizes and colours by clicking top-right of the screen. Most of the questions are at A-level standard, but some are at university level, so don't panic if some make no sense to you (yet)!

We have found that the most effective way of using this resource is to try the questions with pen in hand, calculator at the ready, friends by your side etc, but with a serious intent to get the question right! That way, if you do go wrong, you can compare your attempt with our solution and identify where you went wrong. Educationalists call this 'formative assessment'. It is possible you may still be stuck, or simply disagree with us! Try clicking the Related material button for useful links or, even better, ask your teacher. It is quite rare that a question is wrong, so if your teacher agrees you have found an error, ask him/her to take a screen shot and send it to us please. (Teachers - you should give a prize in this case e.g. a chocolate bar!)

Teachers can set up their own tests by clicking the 'Teacher Interface' link above and registering. (Temporarily this may produce errors and hence need us to activate your account which happens every few days and we will send you a confirmation email if need be.) Teachers they can monitor their students' performances (nobody else can see the students' data) and award marks, usually in conjunction with a traditional exam (often based on extended versions of these questions, perhaps with a subjective element such as 'comment on your results' etc). Unregistered users can still enhance any sort of learning material by adding 'Try one yurself' links. This is trivially easy to do by copying and pasting he URL that appears at the top of an individual question window, or, to select a whole subtopic, by modifying the following link:* , replacing the * with the pid number that is displayed top right in the subtopic's question list frame after you have selected that subtopic from the main tree structure. This will help students find what they need.

We have added Google's translator facility to the questions. Whilst this is not perfect, it may help you if you are studying in another language, but we advise you not use it if you are studying in English. We do not take responsibility for any inaccuracies in translation. Alternatively, just right click on your browser and select 'translate'.
