We are going to install flags on the playground at intervals of 20 meters (m). If there are 12 flags and the circumference of the field is 200 meters (m), how many flags are left?
12 200 20 [OP_DIV] [OP_SUB]
var_a = 12
var_b = 200
var_c = 20
var_d = var_b / var_c
var_e = var_a - var_d
print(int(var_e))
