05 - Binary Addition

 1. The following image shows all the rules of Binary addition. For instance in Binary 0 + 0 = 0. And 1 + 1 = 0 carry 1. Look carefully at all the rules shown in the image and state whether it is True (correct) or False (incorrect)

  False

  True

 2. The first binary addition example has been done for you. Complete the second and select the correct answer from the options below.

  Answer: 1101

  Answer: 1111

  Answer: 00000

  Answer: 00011

 3. Watch the following video that demonstrates binary addition. Where does the student go wrong in his calculation?

  The student has not made any mistakes

  1 and 1 always gives 0 carry 1, but the student wrote 1 (instead of 0 in the third column from the right)

  1 + 0 should be 0, so the student should have written 0 each time there was a 1+0

  1 + 1 should give 2, and so the student should have written 2, instead of 1.

 4. What is the result of the following Binary addition?

  00101110

  11111001

  00000001

  10101010

 5. What is the outcome of this Binary addition? Select one of the options below.

  00011100

  11100011

  11100001

 6. This image would not make sense to most people in the same way that Binary addition wouldn't make sense! What does the T-Shirt message mean?

  10 is a high number so it is saying that a high number of people don't understand Binary

  10 is 2 in Binary ....so it is really saying: There are 2 types of people in this world...!

  I have no idea what it means!

  It means nothing ...10 is not a Binary number so the message doesn't make any sense.

 7. In the ordinary decimal mathematics that you do in Math every day, 1 +0 = ?

  0

  2

  1

  10

 8. In Decimal 0 + 0 = 0 and in Binary 0 + 0 is equal to .....

  00

  This cannot be done

  0

  1

 9. In Decimal 1 + 1 = 2. But in Binary 1 + 1 = 10. This is also written as:
Note: 1 + 1 = 2 and in Binary 2 is 10! 

  0 Carry 1

  10 Carry 10

  1 Carry 0

  1 Carry 1

 10. In Binary addition 1 + 1 + 1 would equal 1 carry 1. (and that is written in Binary as 11) True or False?

  False - this is wholly incorrect

  True, because 11 is 3 in binary

  False. Just False.

  True - because 1 + 1 + 1 cannot be achieved in Binary so is shortened to just 11
