## Perform the following binary subtractions of unsigned binary numbers.

Perform the following binary subtractions of unsigned binary numbers. Convert your answer to decimal.
i) 101001012 – 010010012 ii) 110110102 – 100100112
b) Repeat the calculations above but for when the binary numbers are in two’s complement form. Comment on the results of the two methods used, noting and discrepancies.
2. Find the sums of the following unsigned hexadecimal numbers. Indicate whether or not the sum overflows an equivalent 8-bit binary result.
a) 1116 + 2216 b) 1716 + 3516 c) FA16 + CE16 d) BA16+ A1316
