I mistakenly subtracted a certain number that should have been added to 5.46, and the result was 3.97. Find the result of the correct calculation.
5.46 5.46 3.97 [OP_SUB] [OP_ADD]
var_a = 5.46
var_b = 5.46
var_c = 3.97
var_d = var_b - var_c
var_e = var_a + var_d
print('{:.2f}'.format(round(var_e+1e-10,2)))
