Calculate the sum and difference of the given 8-bit unsigned binary numbers. All calculations must be done in binary. Show your work.

10010101 + 00101110 = 1 1 0 0 0 0 1 1 , 10010101 - 00101110 = 0 1 1 0 0 1 1 1,

01101101 + 01110011   = 1 1 1 0 0 0 0 0 , 01101101 - 01110011 = - 1  1 1 1  1 0 1  0

Explanation:

10010101 + 00101110 =   1 0 0 1 0 1 0 1

                                    + 0 0 1 0 1 1 1 0

                                       1 1 0 0 0 0 1 1

In binary, 1 plus 0 is 1, but 1 plus 1 ( which conventionally is two) is divided by 2 and the result is carried-out, while the remainder is used as the answer.

10010101 - 00101110 =   1 0 0 1 0 1 0 1

                                   - 0 0 1 0 1 1 1 0

                                     0 1 1 0 0 1 1 1  

Subtraction in Binary calculation, a borrow to a 0 value is equal to two, this law is implemented in a case where 1 is subtracted from 0 ( which is impossible).

01101101 + 01110011   =   0 1 1 0 1 1 0 1

                                   + 0 1 1 1 0 0 1  1

                                      1 1 1 0 0 0 0 0

01101101 - 01110011   =   0 1 1 0 1 1 0 1

                                   - 0 1 1 1 0 0 1  1

                                   - 1  1 1 1  1 0 1  0

At the end of the subtraction, if the value subtracted from in less than the subtracted number, two is borrowed and the result becomes negative or signed.

the printer can be used in a both wired and wireless network, only one of the connection methods can be used at one time when the wireless setting is enabled, the wired (ethernet) setting is disabled.

but first you need to

`connect the cord to your computer

`open settings app from the start menu

`click devices

`than click add printer or scanner

and than you should be able to do it from there, if not let me know i can you! : )
