I have started my first year of studying Maths at Oxford University. I enjoy teaching Maths and have been extremely passionate about it since the start of my academic career. I am here to help students of any age prepare for their exams (GCSE, AS/A Level etc), as well as casual learners who are just looking to improve their skills. It is great to see people succeed, and I would love to be part of your success story!
I have just finished Sixth Form, and often helped my classmates when they were struggling with classwork and exam questions. During my time at secondary school I was once asked to cover lessons for my own year group!
As a tutee you will learn the tips, tricks and shortcuts I created and used during my GCSEs and A Levels - I will make sure you understand the necessary concepts so that you can get through your qualification with confidence.

Modulus, also known as absolute value, takes whatever's between the |straight brackets| and makes it positive. For example, |3|=3, and |-3|=3. Interestingly, if you have any real number x, then |x|=sqrt(x2). Try putting some numbers in and see!
We can't solve a modulus question until we get rid of the straight brackets, but this little trick will do the job every time. If we square both sides of the modulus equation in the last paragraph, we get |x|2=x2. So modulus brackets disappear when we square both sides of our equation. Let's try it...
This trick is great, because the x2 terms cancel out and there's no quadratic equation to mess about with. Beware though, this will not be the case in all questions - if you get a quadratic equation to solve, you may end up with more than one solution. Try these bonus questions and see for yourself:
(1) Solve the equation |x+4|=|x-5|.
(2) Solve the equation |x-3|=|2x|.
(3) Solve the equation |3x-1|=|3-x|.see more
