Assign each letter and a blank space to a number as shown by the alphabet table below:

0 = _ 1 = A 2 = B 3 = C 4 = D 5 = E 6 = F 7 = G 8 = H
9 = I 10 = J 11 = K 12 = L 13 = M 14 = N 15 = O 16 = P 17 = Q
18 = R 19 = S 20 = T 21 = U 22 = V 23 = W 24 = X 25 = Y 26 = Z

Use:
| 1 -2 |
| -3 7 |
to encode the phrase "One Question to go".
I don't understand how to order the phrase into a matrix.
