Answer 2

well, write out your message using the appropriate numerical values

Answer 3

then its just a matter of plugging them thru the matrix ... one by one by one .....

Answer 4

O = 15
N = 14
E = 5
space = 0
Q = 17
U = 21
E = 5
S = 19
T = 20
I = 9
O = 15
N = 14
space = 0
T = 20
O = 15
space = 0
G = 7
O = 15

|15|5|17|5|20|15|0|15|7|
|14|0|21|19|9|14|20|0|15|

[1 -2][15 5 17 5 20 15 0 15 7]
|-3 7][14 0 21 19 9 14 20 0 15]
=
[-13 5 -25 -33 2 -13 -40 15 -23]
[53 -15 96 118 3 53 140 -45 84]

Encoded message is
-13, 53, 5, -15, -25, 96, -33, 118, 2, 3, -13, 53, -40, 140, 15, -45, -23, 84
