The distance from the orchard to the house is 800 meters (m), the distance from the house to the pharmacy is 1300 meters (m), and the distance from the pharmacy to the school is 1700 meters (m). How many meters (m) is the distance from the orchard through the house to the pharmacy greater than the distance from the pharmacy to the school?
800 1300 [OP_ADD] 1700 [OP_SUB]
var_a = 800
var_b = 1300
var_c = var_a + var_b
var_d = 1700
var_e = var_c - var_d
