2010 Puzzlers

I asked my middle schoolers to design problems involving the number 2010 to share with a partner.  I ended up being the logical person to be my 13yo son’s partner.  This is what he gave me.  I haven’t solved them yet.  ;-)  Feel free to take a shot at them.

Using the following integers and an unlimited number of +, -, ÷, ×, and parentheses, create an expression that is equal to 2010.  (You must use all the numbers in the set exactly the number of times they are listed.)

1. {2, 2, 2, 2, 3, 3, 5, 5, 17}
2. {1, 3, 3, 3, 7, 7, 7, 7}
3. {1, 1, 1, 1, 3, 3, 3, 3, 3, 5, 5, 5}
