    I wont do the problems for you. But I can help by giving hints and tips. 1. Remember PEMDAS and you should be fine 2. PEMDAS again. But remember to work out everything on the top before dividing everything by 2. 3. Work from the inside out. First solve whats inside the () and then the [] and then solve the outside. 4. Look at every answer and solve from the inside out like I said on the last problem, one of them should = 22.
