Maths Mark
If you are finding some of your maths difficult to understand then you have definitely come to the right place. Since 2013 I’ve been uploading videos on a variety of topics from algebra, number, geometry and statistics under the name maths3000. I always try to explain the topics in a clear and concise way where possible, so you can quickly get your head around each topic.
Please feel free to leave any comments on my videos, and if you have any maths questions I will try to answer them as quickly as possible. I’d also like to thank everyone for the great feedback I’ve received on you tube over the last few years 😊
