I'm a former flight instructor, now airline pilot in the USA. First off, go out and BUY the book: "Stick and Rudder" by Wolfgang Langweische (USA Test pilot from the 40's) Read it a dozen times...each reading is worth dozens of hours of real flight instruction.
Second: The amount of math is very little. Arithmetic skills like understanding there are 360 degrees in a circle and that the opposite direction of 360 degrees (north, also known as "0'' degrees) is south or 180 degrees.
You will have to know how to add,subtract and multiply and divide. Its not rocket science.
Try to learn in pipers and not cessnas...much more civilized but a bit more expensive. (see the movie, "Goldfinger" for the ultimate Piper product placement)
Be in good health and get your medical certificate before you spend too much money...it would be rotten to spend a fortune on learnin ofl nlyto find ot you are in ill health( you don't have to be wonder woman)
Go out and watch the planes takeoff and land...get a very cheap vhf receiver to listen to the radio calls.
