Position Sum
Position Sum problems code a word by adding the position numbers of all its letters (A=1, B=2, ..., Z=26). The code is a single number representing the total sum. These problems test basic addition skills and alphabet position knowledge.

Introduction to Position Sum
Position Sum problems code a word by adding the position numbers of all its letters (A=1, B=2, ..., Z=26). The code is a single number representing the total sum. These problems test basic addition skills and alphabet position knowledge.
Prerequisites
How to Solve Position Sum Problems
Step 1: Convert each letter of the word to its position number (A=1, B=2, ..., Z=26)
Step 2: Add all the position numbers together
Step 3: The total sum is the code for the word
Step 4: For reverse coding (given sum, find word), list possible letter combinations
Step 5: Verify the sum matches the given code
Step 6: Present the numeric code or decoded word
Example Problem
Example 1: Code 'CAT' as sum of letter positions. Solution: Step 1: C=3, A=1, T=20 Step 2: Sum = 3 + 1 + 20 = 24 Answer: 24 Example 2: If a word is coded as 35 and has letters J, _, _, find possible words. Solution: J=10, remaining sum=25. Possible pairs: A(1)+X(24), B(2)+W(23), C(3)+V(22), D(4)+U(21), E(5)+T(20), F(6)+S(19), G(7)+R(18), H(8)+Q(17), I(9)+P(16), J(10)+O(15), K(11)+N(14), L(12)+M(13) Answer: JAX, JBU, JCV, JDW, JET, JFS, JGR, JHQ, JIP, JJO, JKN, JLM
Pro Tips & Tricks
- A=1, E=5, I=9, O=15, U=21 (vowel positions)
- Sum of A to Z = 351 (useful for full alphabet sums)
- For three-letter words, sum range: minimum AAA=3, maximum ZZZ=78
- Common word sums: CAT=24, DOG=36, SUN=54, PEN=34
- Use average position to estimate word length
- Vowels contribute less than consonants typically
