Examples 
If a and b are both positive, then a + b = a + b

3 + 7 = 10 
If a and b are both negative, then a + b = (a + b)

6 + (2) = (6 + 2) = 8 
If a is positive and b is negative and a has the greater absolute value, then a + b = a  b

8 + (5) = 8  5 = 3 
If a is positive and b is negative and b has the greater absolute value, then a + b = (b  a)
