examples: )
                  -2-4=?
so, the - sign in between changes to + sign 
 actually the sign of 4 is+ve. it turns to negative as shown below,
-2+-4=-6
 formulas
-------
- +  - = +
eg;
-1+ -2= -3
- 5+2= -3<since 5 is greater than 2.> the sign of answer becomes -
if 5+ -2=3<since sign of large no is +ve>

There are various identities and fourmulae for solving integers ...................

1-                                       -(-a) = +a
2-                                       + X+=+    Signs the same: positive answer
3-                                        − × + = -  Signs different: negative answer
4-                                        +  x   -   = -   Signs different: negative answer
5-                                        × − = +  Signs the same: positive answer
 6-                                         + ÷ + = +   Signs the same: positive answer
7-                                          ÷ + = − Signs different: negative answer
8-                                          + ÷ − = − Signs different: negative answer
9-                                           ÷ − = + Signs the same: positive answer


properties-

1- closure property of subtraction

example of subtraction= (-30)-(-9)=(-21)

2-Commutative property under subtraction:

example=  8 – (– 6) = 8 + 6 = 14

3-Associative property under subtraction:

example=5 – (6 – 4) = 5 – 2 = 3
  hope it helps u plzzzzz mark it as the best
