Oh, you mean actual binary numbers. It's not particularly difficult, you just need to remember that it's only in base 2 and you can add them like numbers in any other base. For example, with base 4, when you reach 4, instead of writing 4 you carry it over to another digit, just like in decimal system instead of having a symbol for 10, you carry it over: (base 4) 3 + 1 = 10 (base 4) 33 + 3 = 30 + (3 + 3) = 30 + 12 = 102(18 in decimal) just like (base 10) 9 + 1 = 10 (base 10) 99 + 3 = 90 + (9 + 3) = 90 + 12 = 102 So in base 2, or binary, you do the same: (base 2) 1 + 1 = 10 (base 2) 11 + 1 = 10 + (1 + 1) = 10 + 10 = 100(4 in decimal)

@Jeremy Some people are interested in learning how binary works and how the built in methods were developed

why add them in binary? just add them normally and convert the result to binary

you need to write it in javas binary form eg: int bin = 0b11001011 after adding it to something you can do Integer.toBinaryString(bin) and get the binary as string

aka wasting cpu time and memory. Those built in methods exist for a reason ;)
