Assume youre working on a 4-bit computer that uses a signed 2s complement representation, just as in the text. Answer the following. Add 0011 and 0010. Work out the problem long hand, showing your work and the carries. Subtract 0011 from 0010. Work out the problem long hand, showing your work and the borrows. Multiple 0011 by 0010. Work out the problem long hand, much as you would have in 3rd grade long multiplication. Line up the values, etc. Divide 0011 by 0010. Again, work out the problem long hand and show your work. Assuming the same 4-bit computer with signed representation, give a C expression that computes the requested: Given a number n, compute a word with the lower n bits set to 1. You dont know n in advance. Given a number n, compute a word with the higher n bits set to 1. You dont know n in advance.; Assume youre working on a 4-bit computer that uses a signed 2s complement representation, just as in the text. Answer the following. Add 0011 and 0010.
