A box with 6 billiard balls of equal weight weighs 1.82 kilograms (kg). Find the weight in kilograms (kg) of one billiard ball if the empty box weighs 0.5 kilograms (kg).
1.82 0.5 [OP_SUB] 6 [OP_DIV]
var_a = 1.82
var_b = 0.5
var_c = var_a - var_b
var_d = 6
var_e = var_c / var_d
print('{:.2f}'.format(round(var_e+1e-10,2)))
