takes approximately 30 seconds to complete operations of size N = 10⁹. If FFT was not used, it would take 31.7 years (10¹⁸) using the conventional algorithm formula. N = 10⁹ = 1 000 000 000 operations Without FFT N² = 10¹⁸ = 1 000 000 000 000 000 000 / 1 000 000 000 = 31.7 years Nlog2N = 30 x 1 000
