It was really confusing in the begining because I thought you multiplied all of the numbers by 10 but then I realized they are multiplied it by how many numbes there are. I first did 1+2+3+...19+20 and that equals 210 and you put them in order and them put them backwards under that and you add it. You get the same answer which is 21 and you multiply that by how many numbers there are {in this case its 20} SO 21x20 is 420. and 210 times 2 is 20 so thats how i got my answer!
Thank You!
