Ini berarti bahwa: g(x) = g(-x) untuk semua x nyata h(x) = -h(-x) untuk semua x nyata Menggunakan sifat-sifat ini, kita dapat menyederhanakan ekspresi: f(5) - f(-5) = (g(5) +(5) - (g(-5) + (h) - (-(-5) = (g(5) - (h) - f (h) + (h) + (h) + (h) + (h) + (h) + (h) + (h) + (h) + (h) + (h) + (h) + (h) + (h) + (h) + (h) + (h) + (h) + (h) = 05) = (h) + (h) + (h) + (h) = h) = (h) = (h) = (h) = h) = (h) = (h) = h) = (h) = (h) = h) = (h) = h) = (h) = h) = (h) = h) = (h) = h) = (h) = h) = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h = h"}
