It says focuses not eliminates. I think that this is an important distinction. So what is the differnce?

Wow does this sound like a really exciting summer;) Do they have the option of doing thousands of these problems? I am sure there future client will be really impressed with the fact they can expand cos(AB). Give that man a bonus!!

p.s. not even a 4 function calculator:)?
