1. surely you

a) have a calculator
b) can use a computer. Just type the expressions into google
c) learned arithmetic in the 3rd grade?

If none of these is true, come on back and splain what the problem is.

2. Hi Steve,

Yes, I have a calculator and of course a computer, 3 of them in fact. These are dealing with hexadecimals, and binary numbers, and I am not familiar with either of them. If it were that simple, believe me I would not ask for help.

3. Ahh.. I see from your other post that these must be read as base 2 and base 16 values.

1111 - 1010
This is fairly easy, since you don't have to borrow

1111-1010 = 0101 = 101

101 x 10001
= 101
+ 1010000
= 1010101

a handy calculator that works in multiple bases can be found at

http://ostermiller.org/calc/calculator.html

binary values are entered with a leading 0b, as in 0b101

75/27 in base 16 is 3
enter hex values with leading 0x

5. They were separate questions. It appears that you combined two of them.
