200
200 x 10 + 9 = 2009
220
the sum of 80 + 20 + 90 + 10 = 200
200 + 200 + 200 + 200 + 200 = 1000
Ten plus ten plus ten minus two hundred equals negative one hundred seventy.
9/50 + 7/40 + 2/20 + 8/10 + 6 = 36/200 + 35/200 + 20/200 + 160/200 + 6 = 7 and 51/200
800
200 plus 200 plus 150 plus 150 is equal to 700.
(200-90)+20=10
