Question

If the letters in the English alphabets A to M represent the number from 1 to 13 respectively and N represents 0 and the letters O to Z correspond from −1 to −12, find the sum of integers for the names given below.
For example,
MATH → Sum → 13 + 1 – 6 + 8 = 16
SUCCESS

Sum

Solution


SUCCESS → (−5) + (−7) + 3 + 3 + 5 + (−5) + (−5)

= −12 + 6 + 5 + (−10)

= −6 + 5 + (−10)

= (−1) + (−10)

= −11
