& is the bitwise and operator. You have to look at the binary representation of the numbers to see what is happening: 2 decimal is 0010 binary 1 decimal is 0001 binary 2 & 1 == 0010 & 0001 == 0000 == 0 In your other examples you had 2 & 3 == 0010 & 0011 == 0010 == 2 and 4 & 3 == 0100 & 0011 == 0000 == 0 Does this help?
