- encode 12. Maria has four-digit PIN(Personal Identification Number). She needs to send the PIN to her mother by email. Maria decides to the PIN and uses the process: Maria forms a 2 X 2 Matrix A from the digit of her PIN where: A = |1* digit |3d digit 2nd digit 4h digit She chooses then matrix B 20 6 and calculates AB. 3 6 She performs the encoded message by writing down the four elements of AB and following them with the number of digits of each element. 57|, the encoded message would be 125732942222. She then emailed the 32 94 encoded PIN to her mother. For example: if AB = 12 Find: a. AB, if the encoded message that Maria's mother receives is 4148189722232 ?arrow_forwardFind A-B using the following matrices.please make it readable. thank you.arrow_forward
