You made a mistake in dividing a certain number by 8, so you multiplied it by 8 and added 8 to get 56. Show how much it would be if you did it correctly, to two decimal places.
56 8 [OP_SUB] 8 [OP_DIV] 8 [OP_DIV]
var_a = 56
var_b = 8
var_c = var_a - var_b
var_d = 8
var_e = var_c / var_d
var_f = 8
var_g = var_e / var_f
print('{:.2f}'.format(round(var_g+1e-10,2)))
