1110 (2cc) +9 (10cc) =10111 (2cc)=23 (10cc)
Решение:
1110 (2сс) = 2^3+2^2+2^1 =8+4+2=14 (10cc)
9 (10cc) =8+1=2^3+2^0 =1001 (2cc)
1110 + 14 +
1001 9
--------- -----
10111 (2cc) 23 (10cc)
23 (10cc) =16+4+2+1=10111 (2cc)
------------------------------------------------------------------------------------------
1010 (2cc) -3 (10cc) = 111 (2сс) = 7 (10сс)
Решение:
1010 (2сс) =2^3+2^1=8+2=10 (10cc)
10-3=7 (10cc)
3 (10cc)=2^1+2^0=11 (2cc) ; 7 (10cc)=4+2+1=2^2+2^1+2^0 =111(2cc)
