# Cryptarithmetic problems - eLitmus

## Rules for solving Cryptarithmetic Problems

##
**Each Letter or Symbol represents only one digit throughout the problem**
When letters are replaced by their digits,the resultant arithmetical operation must be correct.
Our aim is to find the value of each letter.
**No two letters represent the same digit (If A = 2, B cannot be 2 and so on).**
**Number can't begin with 0**
Rules are:
**1.** 0 * n = 0
**2.** 1 * n = n
**3.** 5 * odd number = x5
like 5 * 1 = 05 (x = 0)
5 * 3 = 15 (x = 1)
5 * 7 = 35 (x = 3)
5 * 9 = 45 (x = 4)

4. 5 * even number = always 0

like 5 * 2 = 0

5 * 4 = 0
5 * 6 = 0
5 * 8 = 0

**5..** even number * 6 = (x)(even number) where x can be 1/2/4
like 2 * 6 = 12 (x = 1)
4 * 6 = 24 (x = 2)

8 * 6 = 35 (x = 4)
