Why do you get an even number when you add two even numbers?

An even number is always some quantity of 'twos' (2's), and any quantity of twos is an even number. The first even number is a quantity of twos, and the second even number is another quantity of twos. When you add the first quantity of twos to the second quantity of twos, you get a new quantity of twos. Since the new quantity of twos is a quantity of twos, it's an even number.

Signed binary subtraction 000000111001-111010000101 equals 000110101110 right?

Wrong. You don't say whether you are using ones-complement notation or twos-complement notation, but in either case you'd be wrong. Your answer of 000110101110 is 430 decimal, but the correct answer is 435 or 436 depending on which notation you use. Ones-complement notation: 000000111001 - 111010000101 = 000110110011 Decimal equivalent: 57 - (-378) = 57 + 378 = 435 Twos-complement notation: 000000111001 - 111010000101 = 000110110100 Decimal equivalent: 57 - (-379) = 57 + 379 = 436 Note that in ones-complement, converting the sign of any value simply inverts all the bits. So if we invert 111010000101 we get 000101111010 which is 378, thus the original signed value was -378. In twos complement we invert all the bits (as per ones-complement) and add 1, so 000101111010 + 1 is 000101111011 is 379, thus the original signed value was -379. QED.
