When you mistakenly multiply a number by 8, instead of dividing a number by 8 and adding 7, you get 56. If you calculated correctly, indicate the number to two decimal places.
56 8 [OP_DIV] 8 [OP_DIV] 7 [OP_ADD]
var_a = 56
var_b = 8
var_c = var_a / var_b
var_d = 8
var_e = var_c / var_d
var_f = 7
var_g = var_e + var_f
print('{:.2f}'.format(round(var_g+1e-10,2)))
