There are a number of things you can try.
1. Why can't you talk to your teacher? That's always possible or it should be.
2. You can find someone else whom you know that can do math. Attach yourself to them until you can do your math alone.
3. Come here. Answer questions that you can do. Build up your points so that you can ask questions. Ask them. When you find someone on here that consistently knows what they are doing, make contact with them.
4. Offer just slightly more than 5 + 3 points. like maybe 7 and 4
5. Don't cheat. Put up questions that you need explanations for that are homework questions. The mods here are pretty strict, and they are quick to jump on to things that they can prove are cheating.
