  • Verbal Arithmetic

RULES:

You are presented with a phrase which is actually in the form of a mathematical problem, but

the numbers have been hidden by letters (or sometimes symbols).

  • The goal is to identify the value of each letter.
  • Each letter represents one and only one number.
  • You can use the numbers 0-9.
  • ALL standard mathematical rules apply
  • No leading digit can contain zero.

NOTE:. Verbal math games can be useful as a motivation and source of exercises in the

teaching of algebra, because they use the property of number substitution, with representation by letters.

Helps , hints and strategies.

Solving math games puzzle by hand usually involves a mix of deductions and exhaustive tests of possibilities.

For instance, the following sequence of deductions solves Dudeney's SEND + MORE = MONEY puzzle

below(columns are numbered from right to left):






  1. From column 5, M = 1 since it is the only carry-over possible from the sum of two single digit numbers in column 4.
  2. To produce a carry from column 4 to column 5, S + M is at least 9, so S is 8 or 9, so S + M is 9 or 10, and so O is 0 or 1. But M = 1, so O = 0.
  3. If there were a carry from column 3 to column 4 then E = 9 and so N = 0. But O = 0, so there is no carry, and S = 9.
  4. If there were no carry from column 2 to column 3 then E = N, which is impossible. Therefore there is a carry and N = E + 1.
  5. If there were no carry from column 1 to column 2, then ( N + R ) mod 10 = E, and N = E + 1, so E + 1 + R = E mod 10, so R = 9. But S = 9, so there must be a carry from column 1 to column 2 and R = 8.
  6. To produce a carry from column 1 to column 2, we must have D + E = 10 + Y. As Y cannot be 0 or 1, D + E is at least 12. As D is at most 7, then E is at least 5. Also, N is at most 7, and N = E + 1. So E is 5 or 6.
  7. If E were 6 then to make D + E at least 12, D would have to be 7. But N = E + 1, so N would also be 7, which is impossible. Therefore E = 5 and N = 6.
  8. To make D + E at least 12 we must have D = 7, and so Y = 2.
