Firstly you convert it to base 10
ie. 1x2^7 +1x2^6 +1x2^5 +1x2^4 +1x2^3 +1x2^2 +1x2^1 +1x2^0
128+64+32+16+8+4+2+1=255 (in base ten)
mean while, since they are the same base two so they have the same base ten
ie. 255+255=510 (in base ten)
then, you convert it to base two by dividing by two and keeping only the remainder.
Finally, your answer will be 111111110 (in base two)
GOODLUCK DEAR FRIEND
