Integers and Operations On Integers 

Class 7 - Mathematics

1. When two positive integers are added, we get a positive integer.
     e.g. 6 + 4 = 10

2. When two negative integers are added, we get a negative integer.
     e.g.  -6 + (-3) = -9

3. When a positive and a negative integer are added, the sign of the sum is always the sign of the bigger number of the two, without considering their signs.
     e.g.  45 + -25 = 20   and    -45 + 20 = -25

4. Additive Inverse
The additive inverse of any integer a is - a, and the additive inverse of (- a) is a.
e.g.  Additive inverse of (-15) = - (-15) = 15
