a = 1: 13 - a = 2 (S)
a = 2: a + 7 = 9 (E)
a = 3: 15 - a = 5 (I)
a = 4: a - 1 = 3 (A)
a = 5: a + 0 = 8 (I)
a = 6: 12 - a = 9 (C)
a = 7: 11 - a = 4 (E)
a = 8: a + 7 = 8 (B)
a = 9: 11 - a = 4 (E)
a = 10: a + 10 = 15 (U)
a = 11: a + 6 = 18 (I)
a = 12: a - 2 = 12 (D)
a = 13: a + 5 = 20 (E)
a = 14: 20 - a = 4 (C)
a = 15: a + 6 = 25 (B)
a = 16: 4 + a = 10 (S)
a = 17: 18 - a = 5 (N)
a = 18: a - 19 = 3 (R)
a = 19: 20 - a = 2 (M)
a = 20: 5 + a = 14 (T)
a = 21: 20 - a = 3 (E)
a = 22: a + 1 = 22 (R)
