  11

  1.0001E+11

  1111

  0

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

  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.

  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

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

  Answer: 1110001

  Answer: 10101010

  Answer: 0101110

  Answer: 11111001

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

  11100011

  11100

  11100001

 5. 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

 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...!

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

  I have no idea what it means!

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

  0

  1

  10

  2

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

  Answer: negative 0

  Answer: 1

  This cannot be done

  Answer: 0

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

  1 Carry 0

  0 Carry 1

  1 Carry 1

  10 Carry 10

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

  False - because it is not possible to have the number 11 in Binary

  False - this is wholly incorrect

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

  True, because 11 is 3 in binary
