In this question, we need to subtract 18 from 32 and we have to use the binary method, means whatever number we have been given.
00:11
So we will convert this in binary system and then we will perform the operation.
00:17
So here we have 32 in decimal form.
00:21
So to convert this in binary system, so let us see here.
00:26
So this is 1, 2, 4, 8, 16, 32 and 64 and so on.
00:34
So we need 32.
00:35
So this is our 32.
00:37
So here it will be 1 and then 0, 0, 0, 0, 0.
00:43
So the system is binary and we have to take this 8 bit system.
00:49
So we will write here 0 and 0.
00:53
So here we can write 0, 0, 1 and then 0, 0, 0, 0 and 0.
01:02
This will be in binary form.
01:04
Similarly, we can write the binary system for 18.
01:09
So 18 can be obtained if we take 16, 1 and this 2 as 1, rest of the elements will be 0.
01:16
So this is 0, 0, 0, 0, 0, 0.
01:19
That means we can write 0, 0, 0, 1 and again 0, 0, 1, 0 and this will be 18.
01:29
But for minus 18, we need to take the complement of 18 in binary system and then add 1 to this.
01:50
So this is 0, 0, 0, 1, 0, 0, 1, 0.
01:59
So this is 18...
