On addition of -46 and +28 using 2’s complement, we get ____________ Correct Answer -10010

The BCD form is written of the two given numbers, in their signed form. After which, normal binary addition is performed. Augend is 28 and Subtrahend is -46. Augend - 0 0 1 1 1 0 0 .....(a) 2’s Complement of Subtrahend: 1 0 1 0 0 1 0 .....(b) _________________ Addiing (a) and (b): 1 1 0 1 1 1 0 Since, there is no carry, so answer will be negative and 2's complement of the above result is determined. 0 0 1 0 0 0 1 + 1 _________________ 0 0 1 0 0 1 0     Answer: - 1 0 0 1 0

Mr.Rohan while helping the students of Class IV in adding and subtracting fractions observed that several students are not able to complete the addition of two improper fractions. He gave a small test with questions from the addition of proper fractions (one item of addition of two similar fractions, three items from the addition of proper and improper fractions, and four items from the addition of improper fractions). He analyzed the responses of each student and found that nearly 45% of students were not clear in adding proper with improper fractions which were affecting their performance in adding two improper fractions. He, therefore, focused on developing the understanding of improper fractions and their addition with proper fractions after which he proceeded to teach the addition of two improper fractions. Which kind of assessment is depicted by this situation?
