About Explaining Maths
Hi, I'm xplanor.
As my nickname suggests, I explain stuff for people that are finding certain concepts hard to grasp. I'm starting with Mathematics first, dealing with some Irish exam questions.
Many maths videos here are recordings of classes, or tutors writingon whiteboard. Sometimes it's hard to read the numbers, unless you use High Definition Youtube.
I've prioritised clarity and completeness. Numbers and symbols are typed out and fairly big, and also I answer whole questions or issues. Sometimes that means I go too fast, I know. But the videos can always be rewound and repeated.
Good to everybody doing the 2009 Leaving Cert exams!
