For the following binary operations, assume that all the numbers are 8-bit 2s complement numbers. Compute the result for each of the following and verify your result by performing the same operation on the equivalent decimal numbers and comparing the results:

1. (1111 0111)2's + (0000 1100)2's

2. (1110 0010)2's (1110 0100)2's

3. (1111 1001)2's + (0000 1011)2's
