  1. WOW! the video realy helped me to understand the things that i did not know before watching these videos.The question that you put just below are quite easy to do. But i cant do it on here, i cn only do it in my learning log or in my maths book that i’v got in my room.I wrote both of th questions in my learning log so i could go back if i forgot the method.
