Encrypting numbers

Hi all,

What type of cipher can be used to encrypt numbers?

I am looking at the following:

9, 30, -3, 0, 12, 0, 29, 46, 1

21, 42, -7, 9, 12, -3, 21, 30, -3

Code Hint: 1, 2, 1, 3, 4, -1, 0, 2, 0

I know what some of the values should decrypt to:

Ciphertext: 9, 30, -3, 0, 12, 0, 29, 46, 1
Plaintext: 0, 3, x, 0, x, x, x, x, x

Ciphertext: 21, 42, -7, 9, 12, -3, 21, 30, -3
Plaintext: 0, 7, x, 0, x, x, x, x, x

Any ideas?

thanks!
Mary
