  0

  11

  1111

  1.00E+11

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

  1 and 1 always gives 0 carry 1, but the student wrote 1(instead of 0, on 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.

  The student has not made any mistakes

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

  Answer: 0101110

  Answer: 10101010

  Answer: 1111001

  Answer: 11111001

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

  11100

  11100011

  1001001

 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)

  TRUE

  FALSE

 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?

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

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

  I have no idea what it means!

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

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

  2

  10

  0

  1

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

  Answer: 0

  Answer: 1

  This cannot be done

  Answer: 00

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

  0 Carry 1

  10 Carry 10

  1 Carry 1

  1 Carry 0

 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
