Question 1192173
there are four rules to followed when adding two binary numbers:
0+0=0
1+0=1
1+1=10 (binary 2)->write 0 and cary 1
1+1+1=11 (binary 3)->write 1 and cary 1

subtracting two binary numbers:
0-0=0
1-0=1
1-1=0
0-1=1 with a borrow of 1
 

1) 11001110(2) + 100011111(2)

Binary value:

Solution is
...................................1........	1........	1........	1(cary)		
0........	1........	1........	0........	0........	1........	1........	1........	0
1........	0........	0........	0........	1........	1........	1........	1........	1
_______________________________________________________
1........	1........	1........	1........	0........	1........	1........	0........	1




11001110 (2)+ 1100011111(2)= 111101101(2)
