Puzzles (Crookes S10)

A puzzle game was bought for me consisting of 11 puzzles (on paper - see pic) and I had to solve the mathematical problems for each one in order to access an on-line message. No use for the puzzles anymore. The one's in the pic are the ones which are still intact (unaffected when being played). Would anyone like to do them, for fun. I have written the answers on a separate piece of paper. Obviously, you won't access the on-line message. Just thought that someone might like a bit of a brain-teaser to keep them occupied for half an hour. (NO time-wasters, pleased. Collect at the first arranged time). Thank you.
