Mathematics teacher for all students and age is not a factor or level of education to tutor

I have a degree in Electrical and Electronics Engineering.I have scored As in my SATS and KCSE and KCPE exams in my country Kenya. I am currently located in Oxford Wantage. I am willing to teach, encourage practising and learning of topics to improve school grades.I like starting with a body stretch and ensuring the child or adult is comfortable to learn.I ensure they have a good proper lighting and email or call to confirm topics beforehand to avoid confusion.I give assignments and random quizzes to check on progress.
I also allow a child to learn how to use a scientific calculator for complex problems such as quadratic equations,graphs etc.
I also teach multiplication,addition,division,subtraction, differentation,integration,calculus,statistics, algebraic and geometric mathematics etc.
