What a tuple is i can't tell you. it's in the next chapter. A integer is a number. What Im trying to do is that I want all the first numbers of the vectors are added and all the second numbers. So if I have this vector [1.0] [1,1] I try to add 1 and 1 and after that I try to add 0 and 1 and put the answer in a new vector. > > Look up list indexing and see if you can solve it yourself, then return > with any questions that arise from this effort. > > The more you do for yourself the faster and better you will learn and we > will be more encouraged to help. > > How does this sound to you?
