The following table shows the position values of the alphabets: We can also memorize the alphabets so that we do not do any calculation mistakes and also reduce the time to solve answers:  S(19) T(20) R(18) A(1) Y(25) ↓ (+1) ↓ (+1) ↓ (+1) ↓ (+1) ↓ (+1) T(20) U(21) S(19) B(2) Z(26)   M(13) O(15) U(21) R(18) N(14) ↓ (+1) ↓ (+1) ↓ (+1) ↓ (+1) ↓ (+1) N(14) P(16) V(22) S(19) O(15)
