I would also like for this thread to sort of serve as a guide for people who have never played to get into how to play. X3 So by helping myself i can help several others in the same boat as myself.
Well every D&D system is a D20 system, which means you roll a 20 sided die to determine most things such as to-hit and skill checks. I, on the other hand, will teach you of D&D 3.5e. You have your base stats of course which can range anywhere from 3 to 18. The typical way to roll ability stats is to roll four 8 sided dice and drop the lowest. The 6 ability stats are strength, dexterity, constitution, intelligence, wisdom, and charisma. You can guess what these all mean. Each ability has an ability modifier which is calculated by subtracting the ability score by 10, dropping it to closest even number, and dividing it by two. This does mean you can have a negative modifier. Every level you roll whatever your class hit die is (Aka: rogue d6, fighter d10, barbarian d12 etc) and add your constitution modifier. You can get skill points determined by your class. The ranks you can put into skills is your level +3. You also get feats 1st, 3rd, 6th, and every 3rd level after.
So to recap. Say you were a level 3 rogue and level 2 warrior, your HP would be 3d6+2d10+con*5 and skill points equal to (26+int)*8
