Made the mistake of subtracting 43.72 from a certain number, when I should subtract 4.372, and I got 16.398. How much would it be if I calculated it correctly?
16.398 43.72 [OP_ADD] 4.372 [OP_SUB]
var_a = 16.398
var_b = 43.72
var_c = var_a + var_b
var_d = 4.372
var_e = var_c - var_d
print('{:.2f}'.format(round(var_e+1e-10,2)))
