Question

Adam says he can walk 20 feet to the left, then 20 feet to the right and be back in his original position. Is Adam correct? Why or why not?

Answer 1

Yes because if you add 20 to 0 then take 20 from 20 you end up with 0 again, 0 being where you started.

Answer 2

Yes Adam is correct because he went 20ft to the left (20) and the 20ft to the right (-20) if you add these two numbers together 20+(-20) it would equal 0. I hope this helped ^^
