A number is subtracted by 1.9, multiplied by 1.5, and added by 32. And finally, you divided it by 2.5 and you got 20. What is the number, including the decimal point?
20 2.5 [OP_MUL] 32 [OP_SUB] 1.5 [OP_DIV] 1.9 [OP_ADD]
var_a = 20
var_b = 2.5
var_c = var_a * var_b
var_d = 32
var_e = var_c - var_d
var_f = 1.5
var_g = var_e / var_f
var_h = 1.9
var_i = var_g + var_h
print('{:.2f}'.format(round(var_i+1e-10,2)))
