If you accidentally divide the number by 18 and divide it again by 1.8, the quotient is 21 with the remainder of 0.2. Find the remainder of the correct calculation.
21 1.8 [OP_MUL] 0.2 [OP_ADD] 18 [OP_MOD]
var_a = 21
var_b = 1.8
var_c = var_a * var_b
var_d = 0.2
var_e = var_c + var_d
var_f = 18
var_g = var_e % var_f
print(int(eval('{:.2f}'.format(round(var_g+1e-10,2)))))
