In a science experiment, a cryptic code is used to label the amounts of three chemicals: A, B, and C. The code is: SEND + MORE = MONEY, where each letter represents a unique digit from 0 to 9. If the equation is correct, what is the value of the digit represented by 'M'?

Solution
6 — To solve this, we must understand that SEND + MORE = MONEY is a valid mathematical equation where each letter represents a digit. The trick is realizing that when adding numbers, the rightmost digits (D + E) must result in a number that either equals 10 (if there's a carry) or less than 10 (if there's no carry). Given that 'M' appears in both the addition and the result, it's likely involved in a carry. The correct approach involves trial and error with the constraints that each letter is unique and that the addition is correct. Starting with 'M', if 'M' is 1, then 'S' could be 9 (since 9 + a small number could result in a carry), making 'MONEY' 10969 and 'SEND' and 'MORE' 9569 and 1300 respectively, which fits if 'D' is 6, 'E' is 5, 'N' is 9, 'S' is 9, 'M' is 1, 'O' is 0, 'R' is 3, and 'Y' is 9. Thus, 'M' equals 1.
