Math Can Be Reversed
Addition is reversed by subtraction
Multiplication is reversed by division
12 x 8 = 96
96 / 12 = 8

10. Let’s Encrypt “8” and Send It
Education – Partnership – Solutions
Let’s Encrypt “8” and Send It
12 x 8 = 96
12 is the encryption key we agreed on
x is the algorithm
8 is the data that I need to send you
96 is the encrypted message

11. Let’s Receive “96” and Decrypt It
Education – Partnership – Solutions
Let’s Receive “96” and Decrypt It
96 / 12 = 8
96 is the encrypted message
/ is the algorithm that reverses x
12 is the encryption key we agreed on
8 is the decrypted message
