Hello there.... I recently purchased maple10-student edition. I am having trouble trying to use it effectively! I am trying to type in simple maths questions into Maple,but Maple does not seem to recognise it? Ive tried everything......im hoping ill be able to get some help with regards to my questions? My question- im tryind to find the fraction equivalent to the fraction ab/cx ? How do you type that in and get the answer? The same goes with this fraction that im trying to simplify a/b + b/a - c/d = How do i type that in ? And can maple give explanations towards its answers?
