Binary mathematics

Perform your mathematical magic with bits and bytes. Set two sets of bits and click +, —, / or x to make your calculation. A few rules:

When you substract, make sure the second byte is smaller than the first, to avoid that the outcome will be a negative.
Same with division: second byte smaller than first.
Never try and divide by zero!
