Retired from work with local authority in IT. Interested in mathematics, general science, music. Enjoy solving math problems, Sudoku and similar puzzles, and helping others to solve them. Studied and graduated in maths and physics at Liverpool University in the 1960s.
My philosophy for answering questions in Math Homework Answers: read questions carefully; answer clearly and make sure each question has been answered as far as possible; tackle some difficult questions, and answer easier ones to make up for time and effort spent on the trickier ones!
