By the way 能and 可以 also an interrogative My english is not good enough ,i hope this can help you

A difficult question,hah~~ 会 = can 能 = be able to do 可以=will/could/may Thanks~

I have to say that N.V and 豆子 did NOT answer your question very correctly. So, let me explain. 我会做这道题。I can solve the exercise (in the correct way). It implies that I can get the correct answer or find the correct solution. 我能做这道题。It depends on the context. For example, I have the time to work on the exercise, but it does NOT mean that I can 100 percent get the correct solution. It implies something personal (something which I can control) allows me to work on the exercise. 我可以做这道题。Kind of like 能, but it implies something not personal allows me to work on the exercise. For example, may I? (Ask you for the permit). More examples for you to understand these words correctly. 我会做这道题，但是我现在不能做，因为我很忙，没空做这道题。 我会做这道题，可以现在开始做吗? 还是等会？ 我现在能做下这道题，但是我不保证我会啊。(I can work on the exercise right now, but I cannot guarantee that I can work it out.) 能做这道题， basically we do not say that. Generally we say, 你能做（一）下这道题吗？Another example, 你能不能帮我下？It implies that if you can, could you help me in the near future or right away. 下(or 一下), you know, it implies something takes just a while, or for one time.

when referring to a skill, 会and能have the same meaning when referring to a decision, 会and能 are different. 我会骑单车， 我能骑单车 我不会帮你 i dont want to help you 我不能帮你 i want to help but i cant.

Actually, I think they are the same .not really different ~
