SANDI MATEMATIKA
sandi matematika melibatkan proses matematika dalam pembuatan maupun pemecahan sandinya. Prosesnya seperti persamaan dalam matematika.
Contoh:
10a + 4b = 36
4a - b = 4
38-2-18-28-40-44-24-2-8-18-26-18-36
Cara penyelesaiannya, kita harus mencari nilai a dan b terlebih dahulu
10a + 4b = 36
4a - b = 4 | x4
_____________
10a + 4b = 36
16a - 4b = 16
____________ +
26a - 0 = 52
26a = 52
a = 2
Maka, jika a = 2
10(2) + 4b = 36
20 + 4b = 36
4b = 16
b = 4
Sandi matematika seperti barisan aritmetika, yang berarti jika a = 2, b = 4, c = 6, dan seterusnya sesuai kelipatannya.
Kemudian sandi di terjemahkan.
38-2-18-28-40-44-24-2-8-18-26-18-36
S A I N T V L A D I M I R
Cara membuat sandi matematika.
Pertama, kita harus menentukan dulu pesan apa yang akan kita sandikan. Misalnya, kita akan menyandikan kata TUESDAY. Lalu kita tentukan nilai dari masing2 huruf. Kita ambil contoh kali ini A = 3 dan B = 6 lalu diteruskan sampai ditemukan Z = 78.
Next, kita 'terjemahkan' kata TUESDAY tadi sesuai nilai huruf dalam kata tersebut
60-63-15-57-12-3-75 Lalu buat persamaannya
Contoh :
4a + b = 18
2a + 4b = 30
