Step 1: +18 is 00010010 Step 2: ~18 is 11101101 Step 3: ~18+1 is 11101110 Looks like you missed the last step, which is to add 1 to the flip of all the bits.
Well, you do what you normally do in addition: add 1 to 1, which is "10" in binary. You write down 0 into the blank and carry the 1 to the next column of digits.
Do the same basic steps, just with 16 dashes instead of 8: +74: 0000000001001010 ~74: 1111111110110101 ~74+1: Add one to the previous number. I'll let you figure this out since I don't want to give out homework answers. :)
1. Draw 16 blanks instead of 8. 2. Number them from 1 to 32,768 under all 16 blanks. (I do this from 1 to 128 in my video). 3. Figure out the binary for +333. 4. Flip all the bits. 5. Add 1 to that result.

Thank you so much I was stuck on this and your explanation was the easiest to understand.
your explanation is really good, you're the best teacher I've ever seen
This was the best breakdown of twos complement I've seen... THANK YOU!!!!
Happy to help. Have a great day.
This helped me alot, you saved me from my test bro I cannot thank you enough.😀
This was so easy to understand!! THANK YOU!!!
I am from Brazil and i had to search in english to find a tutorial simple and beautiful
You should create the Portuguese version of this video to help others in Brazil. I'm glad this video helped you.
@@jcchurch sure! Can i use your vídeo?
@@ramonjales9941Sure. FIgure out a way to download this video and record over the audio with your own.
@@jcchurchthank you!
Bro is saving lives even after 5 years , Cheers Mate !
@@arslanraza4142 I try. Thank you.
Thank you 🙏 best explanation I’ve heard on this topic.
great video, hope you know youre saving students everyday
THANK U SO MUCH, THE OTHER VIDEOS REALLY BE DOING THE MOST. I HOPE MORE PEOPLE FIND THIS VIDEO IF THERYE STRUGGLING
As simple as it is it has really helped me. God bless you
Thank you james! Truly appreciate timing !
Glad you like my super short video.
thank you i had this confucius for a long time
You made my life easy
thank you sir
Two's complement made EASY!👍

Hi! How to convert two's complement number back to denary with the same number (-57)?
Sure. I can do that.
so so soo helpful and short. Prosper
Thank you, thank you. I try. Should I do now super short videos?
this is good i enjoyed
Simple and understandable😎👌
thanks so much for a brilliant video
why did you add the dash 128 if we can represent 57 only with 6 bits(only until dash 64)?
A full byte is 8 bits. That's all.
Worth to add that bit 7 (MSB) is not 128, it's a sign bit. Otherwise it might be confusing, e.g. how would you convert -150 into binary?
Well, you can't. That's not in the spec for 8 bits.
2's compliment doesn't use a sign bit.
help how do u convert -18 into binary because the binary of 18 is 10010 but if I do your trick it will become 11101101 and its wrong
Step 1: +18 is 00010010
Step 2: ~18 is 11101101
Step 3: ~18+1 is 11101110
Looks like you missed the last step, which is to add 1 to the flip of all the bits.
@@jcchurch wow ok thanks!
so it is like adding 11101110+00000001?
Nicely Explained
❤
Short but to the point
I could have included the story about how this was my grandmother's favorite way to encode integers from the old country.
bro saaved my lfe
thank you so much
thanks man !
bro. bro BROO thank you so muchh!
straight direction to the point no zig zagging
@@tareq5264 Yeah. I wanted to cut to the chase.
Tysm!
Thank you easy pizi
how can I know if the binary code represents a negative numbers ? and how can Convert it to decimal again
You know because you intended to store a binary sequence as two's complement.
What if we get a 1 at the end,so do we still need to add a 1 to it
Well, you do what you normally do in addition: add 1 to 1, which is "10" in binary. You write down 0 into the blank and carry the 1 to the next column of digits.
hi. how would you convert -74 to 16 bit binary? Thanks
Do the same basic steps, just with 16 dashes instead of 8:
+74: 0000000001001010
~74: 1111111110110101
~74+1: Add one to the previous number. I'll let you figure this out since I don't want to give out homework answers. :)

Hi first step how to get 01 first line
Hi how do you convert -333 into binary(16bit)? Plz help
1. Draw 16 blanks instead of 8.
2. Number them from 1 to 32,768 under all 16 blanks. (I do this from 1 to 128 in my video).
3. Figure out the binary for +333.
4. Flip all the bits.
5. Add 1 to that result.
@@jcchurch Thnx mate. I finally understand it.
thx
Thank uuuuuuuuuu
No problem!
why is it 8 dashes?
There are 8 bits in one byte. If you want to support larger numbers, you'll need to go up to 16 bits, 32 bits, or 64 bits.
Why add 57 with 1
Those are just the steps to two's complement. There are longer videos on this topic that get into the "why".
Legend😅
isn't -57 two's complement ==> 0011 1001 ?
"0011 1001" is +57.
YAY
banger
Sorry, but this is wrong, you forgot to substract 1 from 57, than switch 1 and 0
The math works out either way.
Right
