Why are signs got reversed in subtraction?

Hi!
Here is the answer to your query.
 
Let two integers be a and b
Now, ab = – (–a) + (–b)
  = – [(–a) + b]
  = – [b + (–a)]
  = – (ba)
Thus, the sing of the result is changed when order of two winters are changed while subtracting then.
 
Hope! You got the answer of your query.
Cheers!
