Hey guys, I've got some math problems for all of you :cool:! Problems are sorted according to their difficulty; easier ones are on top.
Rules:
-No cheating!
-You may use a four function calculator or a standard scientific calculator. Nothing else please (no graphing calculators, CAS, Java, etc.) Yes, you may use pencil, paper, ruler, reference books, etc.
-Try to do them without looking at the [possible] solutions below.
-Feel free to ask for hints, though I may or may not give them. It depends.
-You may collaborate with other people or forum users.
-I strongly encourage you to show your work and post it here, but you don't have to if you can't.
-Don't make random guesses when solving the problems.
-Don't worry if there are problems you can't do; just do the ones you can.
Good luck have fun :D!
