How to differentiate negative binary from positive?

I do understand by reversing binary bits and adding 1 to the end would convert positive value to negative, for example:
Decimal = 53
Binary = 00110101 = (+53)
Negative Binary = 11001011 (-53)
But my concern is that 11001011 could also represent positive decimal 203.
so how can I explain to something that 11001011 is (-53) and not(+203)
Thank you :)

Kindly have a look at signed number representation.
