1-4: Signed and Unsigned Binary

[@MarqZePancakeNinja]

Thank you for this video! I'm going to college online so I got get to actually see these conversions done. This cleared up so much for me!

Signed integers are represented in 2's complement form. Non-negative integers are just converted to binary to find the 2's complement form. For negative integers, the absolute value of the negative integer is first converted to binary and then that binary number is converted to its negative value by taking the 2's complement of it. So 4 is 00000100 and -4 is 11111100 if we restrict ourselves to an eight bit representation of signed integers.

Thanks , this 12 minutes video delivered what my Prof. couldn't in a five lectures time .

[@kiranbandal]

Awesome video.These concepts were explained so neatly.Thanks a lot.Appreciate your efforts.

[@aerofart]

It would be nice to see a video on decoding a signed binary value to decimal - the reverse of this process.

[@nanohe-yj2ee]

Very clear and great video.

[@dheylinantigua]

thank you (so helpful I was a little behind in my class because I didn't know how to get the signed binary)

[@dwerk3]

This was such a great help, thank you!!!

[@NoogahOogah]

That made a lot of sense! Great explanation. Thanks, Mr. Lee

[@Space-Industries]

Great explanation, thank you. Do you have more on this topic?

[@marwinjacinto301]

my professor's slide show says, 11111011 is -123.... he added all the values to the left, and labeled the first 1 as a negative.... I'm confused

[@Mat-vb8er]

Great job Kent Lee! Thanks!

[@susanarodriguez9830]

What can i do in order to subtract a negative number from a positive number for example 15 - (-3)

[@rodmiami]

Best explanation ever !!! Very good

[@CSProfessor]

The complement of this number would be 10 in binary, which is 2 base 10. Adding one would make it 3. So this number is -3, not -4.

thanks, im studying computer science and this really helped me understand it :)

[@ykd3529]

Thanks for the video it taught me alot

[@seaweedguru]

42 equals the answer to the universe!

[@jsmithmusic4]

shouldn't -4 is 11111101, because first we find the one complement and add it to one to give us the 2's complement which is -4 ,or just find the one complement and that should be the -4 .

[@Shanthakumar]

Awesome teacher..........!

[@dydxdydududx]

I watched this video to figure out what is "Unsigned Binary". I now know what 1's comp and 2's comp binary are, but what is "Unsigned Binary"? Can -42 be represented in binary without using 1's comp or 2's comp, or not? Thanks.
