Question

The difference between two binary number 10010000 and 1111001

Answer 1

Answer:

00010111

Step-by-step explanation:

First number 10010000

second number 1111001

1     0     0      1      0      0      0     0

-      1      1       1      1       0      0     1

-------------------------------------------------

0   0     0       1     0       1       1      1

--------------------------------------------------

So basically 4 are some rules which you need to follow:

1. 1 - 0 = 1
2. 1 - 1 = 0
3. 0 - 0 = 0
4. 0 - 1 = 1    

(Because when zero takes 1 as carry from its left side number, '0' will become '10' which is equal to '2' so 2-1=1 and if that '10' further gives carry then it will become '1' not '0')
