Method : Same as in Decimal system, but highest possible number is 1.
Start at the last digits
1+1 = 0 and carry one
Second place is 1+1+the CarryBit 1 =1 and carry one.
Third place is 1+0+the CarryBit 1 = 0 and carry one.
Fourth place is 0+0+the CarryBit 1 = 1 and carry zero.
Fifth place is 0+1 and No CarryBit = 1 and carry zero.
Sixth place is 1+0 and No CarryBit =1 and carry zero.
Seventh place is 1+1 and No CarryBit = 0 and carry one.
Eighth place is 0+0 + the CarryBit 1 = 1 and carry none.

If you simply add numbers the answer is the sum of those numbers.
There are no two real numbers that do, but two complex numbers do: (3.5 + i 3.5 √23) and (3.5 - i 3.5 √23) If you want them to add to 7 and multiply to -294, then the two real numbers -14 and 21 work. Or if you want them to add to -7 and multiply to -294, then the two real numbers 14 and -21 work. To add to -7 and multiply to 294, the following two complex numbers work: (-3.5 + i 3.5 √23) and (-3.5 - i 3.5 √23)
