5 - 10 = -5
B'00000101' - B'00001010' = B'11111011'

Now if I have to take this result and add it to say 20, then this would
immediately overflow and everything would go wako, am I correct?

No, try it yourself.  Everything will be fine as long as the values stay
within the representable range for the number of bits you are using.  With 8
bits this range is -128 to +127.
