Hi guys, I just want to let you know that I've made an app for people studying mathematics, where you can get help from a mentor instantly and for free. You can sign in with Google or register athttp://bubblemaths.com/ You can then upload any maths problems and we'll solve them step-by-step for you! If you would like to Mentor, and you have an A/A* at both GCSE and A-Level Maths/Further Maths, please PM me!
