A = 10011001 (In 8 bit two's complement)
B = 11010111
A = Decimal value
$1\times 2^7+0\times 2^6+0\times 2^5+1\times 2^4+1\times 2^3+0\times 2^2+0\times 2^1+1\times 2^0$
$=128+60+00+16+8+0+0+1$
$=153$
B = $1\times 2^7+1\times 2^6+0\times 2^5+1\times 2^4+0\times 2^3+1\times 2^2+1\times 2^1+1\times 2^0$
$=215$
A + B = 153 + 215 = 368
Binary of 368 = 101110000
There is carry in Addition
