1. For each problem below, convert the base-10 numbers to binary and then perform the arith- metic on the binary representation of the numbers. Give the result in binary and base-10, where the base-10 value is by interpreting the result as an 8-bit signed integer in two's com- plement. If an overflow or carry occurs, say so. By carry, I am only referring to a carry out of the most significant bits added. Assume each number is an 8-bit signed integer that uses (a) 640 6210 (b) 10010 3010 (c) -7010 +5010 (d 123-1410
