There are a total of 20 telephone poles at 25m (m) intervals between Seokgi's and Dongmin's houses. If there is no telephone pole in front of their houses, what is the distance in meters (m) between Seokgi's and Dongmin's houses?
20 1 [OP_ADD] 25 [OP_MUL]
var_a = 20
var_b = 1
var_c = var_a + var_b
var_d = 25
var_e = var_c * var_d
print(int(var_e))
